The Arbiter
The Arbiter is AI entity that observes your every move. Using local LLM (Ollama, llama3), the Arbiter judges your actions, talks to you through an Altar, and makes your world based on your choices.
Key Features
- Big Brother is watching you: The Arbiter tracks your kills, builds, deaths, and interactions
- Karma: Your reputation shifts from Blessed to Damned based on how you play.
- Interaction: Use the Altar to talk directly to the AI. It remembers your history and will mock or praise you accordingly
- Actions: Over 10 unique events can be triggered by the AI, ranging from gifting items to Extreme Punishments like void pulls, lightning strikes, or structure spawns
- The Ascension Path: Reach high karma to ascend! Choose to become a Monk or an Angel
- The Path of Damnation: Low karma or practicing forbidden arts with the Book of Satan may lead to eternal torment in specialized hell dimensions.
