Cosmos
Mini Galaxy
Generate a small seeded galaxy and inspect the stars, planets, and uncertainty behind it. It shows possibilities; it is not a catalogue.
System Generator
Turn a seed into one star system, then watch the planets, moons, and belts move. The physics is simplified, but the layout stays deterministic and readable.
World Generator
Observe a world from orbit. Pick a planet or moon, spin the view, and inspect its surface, sky, host body, and detection notes.
Fantasy
Character Forge
Create a level 1 SRD 5.1 character, choose the basics, and print the sheet. Choices stay in your browser.
DM Toolkit
Run a table from a dense browser console: dice, SRD creature stat blocks, NPCs, weather, locations, factions, and initiative.
Zork Terminal
Play Zork I–III in the browser. The interpreter and saves stay local. Start: I · II · III
