I've been providing work on BL on and off for a while, and am not official in any way, but I think the policy has been to share the work. Maybe we could trade. I've been following your mod for a while and thought the various winged men units could be turned into tengu. Some of the others could just as easily be used for other critters.
While I don't speak for Rinsui, and he's the word on this, is there any chance you guys could return the favor and share a unit or two?

Best of luck on Mythology, by the way. Love the minotaurs and centaurs.
