A fanclub for everybody's favorite maternal eldritch abomination and resident dragon goddess, Tiamat! There doesn't seem to be terribly much fanart of her yet even though her design is (dare I say it) pretty damn hot and a lot of what is there is rather blatantly NFSW (as can be expected from one who goes literally topless all the time) but I think there's at least enough to get things started. And besides, maybe others around here can scrounge up more from Pixiv and the like (which I never frequent).
I'll be starting this off with one my favorite arts of her. Source is pate from Pixiv, in case anyone's curious.
SFW, but just barely
