-# Entity Package
-
-The Entity package provides the core combat and magic systems for EverQuest II server emulation. It extends the base Spawn system with combat capabilities, spell effects, and character statistics management.
-
-## Overview
-
-The Entity system is built on three main components:
-
-1. **InfoStruct** - Comprehensive character statistics and information
-2. **SpellEffectManager** - Manages all spell effects, buffs, debuffs, and bonuses
-3. **Entity** - Combat-capable spawn with spell casting and pet management
-
-## Architecture
-
-```
-Spawn (base class)
-  └── Entity (combat-capable)
-      ├── Player (player characters)
-      └── NPC (non-player characters)
-```
-
-## Core Components
-
-### InfoStruct
-
-Contains all character statistics including:
- Primary attributes (STR, STA, AGI, WIS, INT)
- Combat stats (attack, mitigation, avoidance)
- Resistances (heat, cold, magic, mental, divine, disease, poison)
- Experience points and currency
- Equipment and weapon information
- Group and encounter settings
-
-**Thread Safety**: All access methods use RWMutex for safe concurrent access.
-
-### SpellEffectManager
-
-Manages four types of spell effects:
-
-1. **Maintained Effects** - Buffs that consume concentration
-2. **Spell Effects** - Temporary buffs/debuffs with durations
-3. **Detrimental Effects** - Debuffs and harmful effects
-4. **Bonus Values** - Stat modifications from various sources
-
-**Key Features**:
- Automatic expiration handling
- Control effect tracking (stun, root, mez, etc.)
- Bonus calculations with class/race/faction requirements
- Thread-safe effect management
-
-### Entity
-
-Combat-capable spawn that extends base Spawn functionality:
-
-**Combat Systems**:
- Health/Power/Savagery management
- Combat state tracking (in combat, casting)
- Damage resistance calculations
- Speed and movement modifiers
-
-**Magic Systems**:
- Spell effect application and removal
- Concentration-based maintained spells
- Bonus stat calculations
- Control effect immunity
-
-**Pet Systems**:
- Multiple pet types (summon, charm, deity, cosmetic)
- Pet ownership and dismissal
- Pet spell tracking
-
-## Usage Examples
-
-### Creating an Entity
-
-```go
-entity := NewEntity()
-entity.GetInfoStruct().SetName("TestEntity")
-entity.GetInfoStruct().SetLevel(50)
-entity.GetInfoStruct().SetStr(100.0)
-```
-
-### Managing Spell Effects
-
-```go
-// Add a maintained spell (buff)
-success := entity.AddMaintainedSpell("Heroic Strength", 12345, 300.0, 2)
-
-// Add a temporary effect
-entity.AddSpellEffect(54321, casterID, 60.0)
-
-// Add a detrimental effect
-entity.AddDetrimentalSpell(99999, attackerID, 30.0, 1)
-```
-
-### Stat Calculations
-
-```go
-// Get effective stats (base + bonuses)
-str := entity.GetStr()
-sta := entity.GetSta()
-primary := entity.GetPrimaryStat()
-
-// Recalculate all bonuses
-entity.CalculateBonuses()
-```
-
-### Pet Management
-
-```go
-// Set a summon pet
-entity.SetPet(petEntity)
-
-// Check pet status
-if entity.GetPet() != nil && !entity.IsPetDismissing() {
-    // Pet is active
-}
-```
-
-## Constants and Enums
-
-### Pet Types
- `PetTypeSummon` - Summoned pets
- `PetTypeCharm` - Charmed creatures
- `PetTypeDeity` - Deity pets
- `PetTypeCosmetic` - Cosmetic pets
-
-### Control Effects
- `ControlEffectStun` - Cannot move or act
- `ControlEffectRoot` - Cannot move
- `ControlEffectMez` - Mesmerized
- `ControlEffectDaze` - Dazed
- `ControlEffectFear` - Feared
- `ControlEffectSlow` - Movement slowed
- `ControlEffectSnare` - Movement impaired
- `ControlEffectCharm` - Mind controlled
-
-## Thread Safety
-
-All Entity operations are thread-safe using:
- `sync.RWMutex` for read/write operations
- `sync.atomic` for simple state flags
- Separate mutexes for different subsystems to minimize lock contention
-
-## Integration with Spawn System
-
-The Entity extends the base Spawn class and requires:
- `spawn.NewSpawn()` for initialization
- Access to Spawn position and basic methods
- Integration with zone update systems
-
-## Future Extensions
-
-Areas marked with TODO comments for future implementation:
- Complete item and equipment systems
- Combat calculation methods
- Threat and hate management
- Group combat mechanics
- Spell casting systems
- LUA script integration
-

- `info_struct.go` - Character statistics and information
- `spell_effects.go` - Spell effect management system

+// Package factions provides comprehensive faction management for the EQ2 server emulator.
+//
+// The faction system manages relationships between players, NPCs, and various game entities.
+// It includes consideration levels (con), hostile/friendly relationships, and dynamic faction
+// value changes based on player actions.
+//
+// Basic Usage:
+//
+//	// Create a new faction
+//	faction := factions.New(db)
+//	faction.ID = 1001
+//	faction.Name = "Guards of Qeynos"
+//	faction.Type = "City"

+//
+//	// Load an existing faction

+//	loaded.PositiveChange = 100
+//	loaded.Save()
+//
+//	// Delete a faction
+//	loaded.Delete()
+//
+// Master List Management:
+//
+//	masterList := factions.NewMasterList()
+//	masterList.AddFaction(faction)
+//
+//	// Lookup by ID or name
+//	found := masterList.GetFaction(1001)

+//
+//	// Add relationships
+//	masterList.AddHostileFaction(1001, 1002)  // Guards hate bandits
+//	masterList.AddFriendlyFaction(1001, 1003) // Guards like merchants
+//
+// Player Faction System:
+//
+//	playerFaction := factions.NewPlayerFaction(masterList)
+//	playerFaction.IncreaseFaction(1001, 100)  // Gain faction
+//	playerFaction.DecreaseFaction(1002, 50)   // Lose faction
+//
+//	// Check consideration level (-4 to +4)
+//	con := playerFaction.GetCon(1001)
+//	if con <= factions.AttackThreshold {
+//		// Player is KOS to this faction
+//	}
+//
+// The system integrates with the broader EQ2 server architecture including database
+// persistence, client packet updates, quest prerequisites, and NPC behavior.
