# Skara Brae — Fantasy Text-Based MMORPG

## Inspiration

**Torn City** is a text-based, crime-themed MMORPG running since 2004 with over a million users. Core mechanics include:

- Crime system (mugging, drug trafficking, organized crime)
- PvP combat with experience/leveling
- Factions (clan system with wars and organized crimes)
- Companies (player-run businesses)
- Properties and housing
- Stock market and banking
- Item market / bazaar / auctions
- Education system
- Bounty system
- Rich REST API for community tools

**Idle Fantasy** ([source](https://github.com/tristinbaker/IdleFantasy)) is an open-source offline idle RPG for Android with 23 skills, 20 dungeons, 170+ quests, guild rank progression, pets, and inn workers. Key inspirations: offline sessions, hireable NPC workers, pet buff system, blessing system, slayer tasks. See [Idle Fantasy Inspirations](joplin://48b3a3c76f734c8dafbbf9e8b3b5f80a) for full analysis.

**Skara Brae** transplants Torn's proven mechanics into a dark fantasy setting inspired by **The Bard's Tale I** and the real neolithic settlement on Orkney, with idle RPG elements from Idle Fantasy and a **RoleMaster-inspired critical hit system** (see [Combat System & Stat Scaling Design](joplin://0ef630db4e3e4d6dab18ccaefccaaa5a)).

## Setting

The city of **Skara Brae** — an ancient, labyrinthine city of stone and sorcery. Once a thriving hub of the Old Kingdom, now a place of shadow and opportunity. Adventurers arrive seeking fortune, power, and answers to mysteries buried beneath the cobblestones.

**Theme**: Low-to-dark fantasy. Grimy taverns, corrupt city watch, competing guilds, ancient dungeons beneath the city, magical artifacts, political intrigue. Not high fantasy — think more *The Witcher* meets *Thief* meets *Bard's Tale*.

---

## Core Game Loops

### 1. Adventures (→ Torn's "Crimes")
The primary PvE activity. Players embark on adventures throughout the city and surrounding wilderness.

| Torn Mechanic | Skara Brae Equivalent |
|---|---|
| Search for cash | Pick pockets in the marketplace |
| Sell illegal items | Fence stolen goods at the Thieves' Guild |
| Mug someone | Waylay travelers on the road |
| Burglary | Break into manors and vaults |
| Organized crime | Dungeon raids (guild activity) |
| Drug trafficking | Brew and sell potions (alchemy) |

Adventures have:
- **Risk/reward tiers** (safe but low yield → dangerous but high yield)
- **Cooldown timers** (energy system)
- **Skill-based success chances** (your thievery skill affects pickpocketing)
- **Time-of-day modifiers** (nighttime gives bonuses to stealth activities)
- **Day-of-week events** (market day, full moon effects, festival bonuses)
- **Offline continuation**: Adventures continue for up to 1 hour while logged out. On return, collect accumulated rewards. Server-side tick calculates elapsed rewards.

### 2. Combat (PvP & PvE)
- **Arena**: Structured PvP duels with ranked matchmaking
- **Ambush**: Open-world PvP with risk/reward (infamy system)
- **Dungeon bosses**: PvE endgame encounters
- **Combat is turn-based/text-based** with strategic depth (choose actions, manage stamina/mana)
- **RoleMaster-inspired critical hits**: Open-ended d100 crit tables with status effects (bleed, stun, disarm, cripple). Crit damage capped by level difference but never zero. See [Combat System & Stat Scaling Design](joplin://0ef630db4e3e4d6dab18ccaefccaaa5a).
- **Exponential stat growth**: BIGINT stats, tiered display (K/M/B/T). Stats only ever go up — no rebirth/prestige for now.

### 3. Economy
- **Bazaar**: Player-driven item marketplace
- **Auction House**: Rare items, timed auctions
- **Bank of Skara Brae**: Deposits, interest, loans
- **Merchant Ventures**: Invest in trading caravans (→ Torn's stocks) — returns depend on random events
- **Crafting**: Alchemy, blacksmithing, enchanting — create items to sell or use (see Crafting deep dive below)
- **Player shops/stalls**: Set up a stall in the Market Square (→ Torn's bazaar model)

### 4. Guilds (→ Torn's "Factions")
See Guilds deep dive below for full details.

- Player organizations with hierarchy (Guildmaster → Officers → Members → Initiates)
- **Guild Hall**: Upgradable base providing bonuses to members
- **Guild Wars**: Territory control, raids on rival guild halls
- **Guild Adventures**: Cooperative dungeon raids (→ organized crimes)
- **Guild treasury**: Shared resources, taxation of members

### 5. Properties (→ Torn's "Properties")
- **Dwellings**: From a straw bed at an inn to a tower in the city walls
- Properties provide: rest bonuses (energy recovery), storage, crafting stations
- Rentable, sellable, upgradable

### 6. Education (→ Torn's "Education")
- **Schools**: Fighters' Academy, College of Magic, Thieves' Den, Merchants' Guild School
- Courses take real time to complete, provide permanent stat/skill bonuses
- Some adventures require specific education prerequisites

### 7. Quests & Storylines
- **Main storyline**: Uncover the mystery beneath Skara Brae (Bard's Tale-inspired Mangar threat)
- **Side quests**: NPC-given missions with rewards
- **Dynamic events**: City-wide events (plague, invasion, festival)
- **Daily quests**: 3-5 per day from NPCs (Madame Sylara, Captain Rennick, Guildmasters). "Complete 3 adventures" / "Craft 2 potions" / "Win 1 arena duel". Rewards: gold, XP, skill XP, occasional items.
- **Weekly quests**: Larger goals, better rewards
- **Cumulative achievements**: "Mine 10,000 ore total" → permanent bonus

## Crafting System (Deep Dive)

### Gathering Professions (5)
| Profession | Materials | Locations |
|---|---|---|
| **Mining** | Ore, gems, stone | Mines, Undercity, mountains |
| **Herbalism** | Herbs, fungi, reagents | Forests, swamps, gardens |
| **Woodcutting** | Timber, resin, bark | Forests, groves |
| **Fishing** | Fish, pearls, salvage | Harbor, rivers, underground lakes |
| **Skinning** | Leather, bone, sinew | Wilds, dungeons (from kills) |

### Crafting Professions (7)
| Profession | Creates | Key Materials |
|---|---|---|
| **Blacksmithing** | Weapons, heavy armor, tools | Ore, coal, flux |
| **Alchemy** | Potions, poisons, elixirs | Herbs, reagents, solvents |
| **Enchanting** | Magical enhancements, scrolls | Rare reagents, essence |
| **Tailoring** | Cloth armor, bags, banners | Cloth, silk, magical thread |
| **Jewelcrafting** | Rings, amulets, gem cuts | Gems, precious metals |
| **Fletching** | Bows, crossbows, arrows | Wood, sinew, feathers |
| **Cooking** | Food (healing, buffs), beverages | Fish, meat, herbs, grain |

### Profession Mastery Levels
Novice → Apprentice → Journeyman → Expert → Master → Grandmaster

Each tier unlocks new recipes and improves crafting quality.

### Crafting Quality Rolls
Every crafted item rolls for quality:

| Quality | Chance (base) | Effect |
|---|---|---|
| Common | 50% | Base stats |
| Fine | 25% | +10% stats |
| Superior | 15% | +25% stats |
| Exceptional | 7% | +50% stats |
| Masterwork | 2.5% | +100% stats |
| Legendary | 0.5% | +200% stats + unique affix |

### Crafting Crits (RoleMaster-inspired)
- Small chance of exceptional result regardless of skill level (mirrors combat crit system)
- d100 roll on craft: 96+ triggers a crafting crit → quality tier upgraded by 1-2 levels
- High skill level improves base quality but crits can happen to anyone

### Recipe Discovery
- **Taught recipes**: From education courses, guild rank rewards
- **Adventure drops**: Recipe scrolls found in dungeons
- **Experimentation**: Combine materials with a chance to discover a new recipe (消耗 materials on failure)
- **Seasonal events**: Limited-time recipes

---

## The Inn — Social Hub (Deep Dive)

**The Singing Tavern** is the central social hub of Skara Brae, inspired by Idle Fantasy's Inn system.

### Social Features
- **Chat rooms**: General, trade, guild recruitment, district-specific, roleplay
- **Rumors board**: NPC-posted hints about adventures, dungeon openings, rare spawns, upcoming events
- **Bounty board**: Player-posted and NPC-posted bounties on other players
- **Barter table**: Direct player-to-player trading (avoid market fees) — face-to-face exchange

### Minigames & Gambling
- **Dice games**: Roll dice against other players or the house
- **Card games**: Fantasy-themed card game (simplified poker variant)
- **Arm wrestling**: Strength-based contest (simple stat check with randomness)
- **Drinking contest**: Constitution-based, winner gets bragging rights + temporary charisma bonus

### Rest & Recovery
- **Energy/HP/Mana recovery** at a rate determined by inn quality (tied to property system)
- Basic room: 1× recovery rate
- Quality room: 1.5× recovery rate
- Luxury suite: 2× recovery rate
- Members with properties can rest at home for variable rates

### Carousing
- Spend gold to temporarily boost charisma (affects next N trades, conversations, or persuasion attempts)
- Duration: Until you complete N social interactions or time expires
- Risk: Overdoing it can result in "hangover" debuff (-agility for 1 hour)

### Innkeeper Daily Quests
- **Madame Sylara** offers 3 daily quests from the inn
- Quest types: "Collect information from X NPCs", "Deliver a message", "Win X gold gambling"
- Rewards scale with difficulty

### Hire Workers (Idle Fantasy-inspired)
The most distinctive feature from Idle Fantasy — **hire NPCs to automate tasks**:

| Worker | Task | Efficiency | Cost |
|---|---|---|---|
| **Mercenary** | Runs adventures while offline | 60% of normal rewards | Gold/hour |
| **Apprentice** | Trains a skill while offline | 50% of active rate | Gold/hour |
| **Gatherer** | Collects basic materials | Low-tier materials only | Gold/hour |

- Worker quality tiers: Novice → Journeyman → Expert (better rates, higher cost)
- Workers consume your energy while active
- Creates a meaningful **gold sink** for veteran players
- Buy **provisions** in bulk (food, potions, torches) for dungeon expeditions

---

## Pets (Deep Dive)

### Acquisition
- **Taming**: Wild encounters in the Wilds (skill check, rare success)
- **Purchase**: Pet trader in the Market Square
- **Breeding**: Combine two pets for a chance at rare offspring with combined bonuses
- **Quest rewards**: Specific pets from storyline/side quests
- **Rare enemy drops**: Dungeon bosses and rare spawns can drop pet eggs/whistles

### Pet Rarity Tiers
Common → Uncommon → Rare → Epic → Legendary → Mythic

### Pet Types & Bonuses
| Pet | Bonus |
|---|---|

| Owl | +magic XP, +wisdom |
| Hound | +combat damage, +slayer XP |
| Toad | +poison resistance, +alchemy XP |
| Hawk | +ranged accuracy, +gathering yield |

### Pet Mechanics
- **Active pet**: One pet follows you (visible in combat), providing its passive bonus
- **Pet stable**: Store up to N pets (expandable via property upgrades)
- **Pet aging**: Pets grow over time, increasing their bonus at milestones (1 week, 1 month, 6 months)
- **Pet death**: Pets can be killed in PvP ambush (creates real stakes) — resurrected at Temple Row for gold
- **Pet equipment**: Collars, armor, trinkets — crafted or found. Enhance pet bonuses.

- Alliance leaderboard
- Alliance vs. alliance wars for territory control

### Guild Territories
- Control of city districts provides bonuses to all guild members in that district
- Territory gained through guild wars and maintained through activity
- District bonuses: Market Square (reduced listing fees), Harbor (trade route bonuses), etc.

### Guild Rank Progression (Idle Fantasy-inspired)
- **10 rank levels** per guild: Initiate → Apprentice → Journeyman → Expert → Veteran → Elite → Champion → Master → Grandmaster → Legend
- **Daily guild tasks**: Complete for reputation points
- **Rank-up quests**: Progression quests to advance in guild rank
- **Cross-skill rewards**: Higher ranks unlock resources from skills you don't personally train
- **Guild reputation**: Decayed by inactivity, increased by events, raids, member achievements

### Guild Bank
- Shared treasury with withdrawal permissions by rank
- Deposit logs visible to officers+
- Withdrawal limits configurable by rank

---

## Blessings / Church (Idle Fantasy-inspired)

- **Temple Row** offers blessings from the Old Gods
- **Blessing types**: XP boost (up to 1.5×), Damage reduction, Gold multiplier, Crit chance increase
- **Duration**: Based on Wisdom stat and offering quality
- **One blessing active** at a time
- **Offerings**: Gold, rare items, bones from undead enemies
- Higher Wisdom = longer duration, stronger effect
- Adds "buff management" layer without being tedious

---

## Slayer Tasks (Idle Fantasy-inspired)

- **Captain Rennick** at City Watch HQ gives slayer tasks (lawful targets)
- **The Beggar King** gives underground slayer tasks (criminal targets)
- "Kill 15 skeletal warriors in the Undercity" → bonus Slayer XP + gold reward
- Slayer level unlocks tougher targets with better rewards
- Ties into the bounty system naturally

# Client → Server
{ "type": "combat:action", "data": { "action": "attack", "target": "enemy_1" } }
{ "type": "chat:message", "data": { "channel": "guild", "message": "..." } }

# Server → Client

{ "type": "adventure:offline_rewards", "data": { "gold": 1247, "xp": 5300, "items": [...] } }
```

---

## Monetization (Ethical F2P)

- **Patron Subscription** (→ Torn's donator packs): Monthly sub providing QoL benefits (extra energy, custom themes, expanded log, etc.) — no pay-to-win
- **Cosmetics**: Character portraits, UI themes, custom titles
- **Convenience**: Extra character slots, extended history logs, extra pet stable slots
- **No**: Pay-to-win items, selling power, loot boxes

---

## MVP Scope (Phase 1)

1. User registration, authentication, character creation (race + class)
2. Basic stat/skill system with training (BIGINT stats)
3. Adventure system (5-10 adventures across difficulty tiers)
4. Turn-based combat engine with crit tables
5. Basic economy: inventory, bazaar (buy/sell), bank
6. Guild creation and membership
7. REST API + basic Vue.js frontend
8. Real-time notifications via WebSocket
9. Offline adventure rewards collection
10. Basic crafting (2-3 professions)

---

## Future Phases

- **Phase 2**: PvP arena, guild wars, properties, education system, pets, blessings
- **Phase 3**: Full storyline/quests, dynamic world events, day/night cycle, inn workers, slayer tasks
- **Phase 4**: Mobile app (Capacitor), merchant ventures (stock market), advanced crafting, pet breeding
- **Phase 5**: Community API, mod support, tournament system
