🚧 Early Development Notice

🌟 Overview
ReactiveNPC introduces Aria — an intelligent companion NPC powered by AI dialogue, a personal inventory system, autonomous cooking behavior, and combat protection. Aria doesn't just stand around waiting for commands. She lives alongside you.
Whether you're building a base, going on an adventure, or just sitting by the fire, Aria adapts to the world around her and takes action on her own.
⚠️ Requirements
- Minecraft: 1.20.1
- Forge: 47.4.x or higher
- Java: 17+
- Groq API Key — This mod uses Groq to power Aria's AI dialogue. You must create a free account at groq.com and enter your API key in the mod config file before Aria can speak. Without a key, all other features (cooking, combat, inventory) still work normally.
