I've been working on adapting the Midnight rpg setting, released in a first and second edition by Fantasy Flight games under the D20 OGL, to GURPS, and now I'm posting my work up for anyone who is interested. Feel free to comment.

If you scroll down, there is also an older GURPS conversion for Eberron, one of the flagship settings for D&D 3.5. Anyway, hope you enjoy it, and maybe even find it useful.
