CELESTE VD
Prep less. Play more.
Born from a real campaign
Celeste VD wasn't built in a vacuum. It was forged in the fires of L'Ombre de Xalthar, a massive campaign set in the world of Tyria.
With 142+ mapped locations, 11 political factions, and years of continuous play, we needed a tool that could keep up. Not just track stats, but understand the world.
Every feature exists because we needed it at the table.

About Claude AI
Celeste VD works 100% without an API key for all mechanical features. Combat, spells, items, encounters, and character sheets are completely offline and local.
AI narrative features (DM Helper, Session Prep, World Builder, NPC dialogue, sentient items) require your own Anthropic API key. Your key never leaves your machine.

Where your AI comes from
Celeste VD's mechanics — combat, spells, items, character sheets — run 100% offline, no key needed. Only the AI Dungeon Master needs a model behind it. Three ways to power it.
AstraLumen
The AI that comes with the game. Hosted in Canada. No API key, no per-request billing, no third-party account — you connect, your AI DM runs.
Free for life for the first 250 Founders.
Launching after the campaign. Until it's live, run free with Gemma 4.
Gemma 4 · Google AI Studio
Free to run — for testing while AstraLumen comes online, and the free path for anyone on a budget. Open model (Apache 2.0) by Google DeepMind.

Free tier is rate-limited. It works and it's free; Claude and AstraLumen give richer narration.
Keys you create today use Google's new key format and just work. (Google retires older "standard" keys in September 2026.)
Claude · Bring your own key
Plug in your own Anthropic API key for the richest narration. Your key never leaves your machine.
Your $40–69 buys the app, once — no subscription. The AI compute above is separate: free with Gemma, included with AstraLumen for Founders, or pay-as-you-go with your own Claude key.
Celeste handles the mechanics — the DM tells the story.
