Back earlier this year I wrote up what would be the initial seed for Uldridge City moving over into The Flames Will Die.
It was originally a simple setting for use with Into the Odd, it was all setting with no mechanical alterations. But I never put it out for people to see as I moved away from that spot and went to start working more on having it integrated into the new game system.
By the way, I am pretty sure it had no editing done to it and is meant to leave tons of blanks. But it still is really cool.
