-# 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

+//
+// 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"
+//	faction.Description = "The brave guards protecting Qeynos"
+//	faction.DefaultValue = 0
+//	faction.Save()
+//
+//	// Load an existing faction
+//	loaded, _ := factions.Load(db, 1001)
+//	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)
+//	byName := masterList.GetFactionByName("Guards of Qeynos")
+//
+//	// 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.
