The Underworld Hub
Every Underworld tool,
in one place.
A searchable reference for the rulebooks and a character builder that does the arithmetic for you. Both run entirely in your browser — nothing to install, no account, and nothing you type ever leaves your device.

Works without a signal
Both tools are self-contained. Once a page has loaded it keeps working in a dead-zone venue, and your characters are saved in your own browser.
Always cited
Rules carry the book and page they came from. Reconstructed charts say so, so you know when to double-check the printed table.
