What We Build

Portfolio

One universe, two forms: a seven-volume novel saga being written now, and an RPG where a thousand AI characters live whether you're watching or not. Built by one person, with AI in the loop, in the open.

A Novel Saga × A Living AI World
Cyberpunk × High Fantasy

A multi-agent AI Dungeon Master that runs a procedurally generated cyberpunk-fantasy RPG for multiple human players. Nine specialized AI agents coordinate in real-time — from narrative generation and tactical combat to NPC relationships and moral consequence tracking.

Features a canon story mode with intelligent divergence tracking, where the system gracefully adapts when players go off-script, alongside a fully procedural freeplay mode. AI companions have real personalities, opinions, and the ability to disagree.

How It's Made

The Studio

The workshop door is open. RedStar Foundry is a one-man studio. The novels are written by hand. The world is built in long arguments with AI. The art direction is explored through generative tools first — and will be drawn by human artists after. The game runs on an agent architecture built nights and weekends.

This site is the workshop, not the storefront. What you see here is a universe under construction: gameplay experiments, art direction passes, systems being torn down and rebuilt. Things will change. That's the point.

Under the Hood

The Engine

The same obsession runs through the prose and the code: worlds that keep their own books.

01

Autonomous Characters

A thousand-plus concurrent agents with five-axis personalities, eight archetype clusters, and independent decision cycles — characters with memory, goals, and grudges who act whether you're watching or not.

In Practice
  • Five personality axes: risk, trust, empathy, ambition, volatility
  • Eight archetype clusters with population-level variety
  • Persistent decision cycles firing on timers, proximity, and events
  • 1,000+ concurrent agents with distinct behavioral signatures
02

Persistent Memory

Episodic, emotional, semantic, and working memory per agent — with emotional memory outliving factual by design, and compression that turns old episodes into lived understanding.

In Practice
  • Episodic memory with timestamps, participants, emotional tags
  • Tiered decay: feelings persist longer than facts
  • Compression pipelines distill history into semantic knowledge
  • Embedding retrieval surfaces relevant memories on demand
03

Consequence Systems

Shadow scores, bond dynamics, and betrayal thresholds — moral weight earned through play and read socially by every agent, never chosen from a menu.

In Practice
  • Shadow: cumulative moral weight with velocity tracking
  • Relationship engine: trust, jealousy cascades, resonance
  • Companion betrayal triggered mechanically, not scripted
  • Gossip and reputation propagate through faction networks
04

Production LLM Architecture

LangGraph orchestration, tiered models that scale cost to stakes, context-window management, and full observability — complex AI systems built to run, not to demo.

In Practice
  • Graph-based workflows with conditional routing
  • Frontier models for critical decisions, lightweight for routine
  • Token-aware memory compression across long runtimes
  • Full tracing and observability across agent decision chains
Who We Are

About

RedStar Foundry is led by Taiin — a terrible gamer, obsessive data nerd, movie lover, voracious reader, and chaotic energy all wrapped in one.

By day, AI systems for institutions that can't afford to get it wrong. By night, a universe. The through-line is the same: build worlds where nothing is decoration — every character keeps books, every choice compounds, every light has a bill.

Our philosophy: build things that work at the technical layer at scale. Not wrappers. Not demos. Not pitch decks. Working software and working prose — a thousand NPCs with genuine personalities, and a saga that keeps the same books.
