Sovereign Engine is a production-ready Unreal Engine 5 plugin that brings intelligent, procedural NPC dialogue to your game with a Zero-Hallucination Guarantee.
Powered by local LLMs (Ollama) or cloud AI (OpenAI, Anthropic, Gemini, OpenRouter), it generates contextually aware, rule-validated narrative responses with persistent memory, quest tracking, and world-awareness.
Unlike other AI plugins that blindly pipe raw, unsafe text into your game, Sovereign Engine acts as an impenetrable middleware layer. Our proprietary IntentShield and LogicShield architectures intercept the raw LLM output, validate it against your hardcoded game rules, and force the AI to correct itself before the response ever reaches Unreal Engine. LLMs will never break your game state.
Features:
5-Provider Auto-Routing: Native support for OpenAI, Anthropic, Google Gemini, OpenRouter, and local Ollama.
Custom Payload Override: Define your exact JSON expected data (e.g. {"trade_discount": 0.8}) directly in the BP details panel.
Targeted Memory Management: Dynamically erase an NPC's entire memory, specific conversation history, or specific facts/quests using built-in Blueprint wipe nodes!
Universal Constraint System: Restrict actions, items, and dialogue bounds per-NPC to aggressively block hallucinations.
Zero Server Costs Required: Run completely locally for players or securely from your own cloud host.
1-Click Installation: We bundle the highly robust Python SDK directly inside the plugin. No external packages required!
