Here is a collection of tools I have made for gaming in general, and my settings in particular:

NPC Generator for Blades & Black Magic (Ealdun, Middle Lands, Vales, Shaman’s Valley).
Creature Background Generator (Ealdun, Middle Lands, Vales, Shaman’s Valley).
Planned
Demon generator, for Swords & Sorcery.
An Outsider generator, for the Ealdun setting.
Slime generator.
More as I think of them!
