Coincidentally, I was flipping through some older copies of Dungeon magazine recently, and I saw an add for a Dragonlance novel by Margaret Weis, which mentioned Chemosh as a deity in Dragonlance!
It seems Dragonlance has adopted the name as a death god, which is unlike his "real" profile, but which is also fine as the name is kinda obscure. Or, well, it was, I guess. If Dragonlance has used it, then it probably isn't anymore.
Sounds like I'll have to keep looking... My other main choice was Chernobog, which is not only descriptive, but fits as my substrate language is loosely Slavic-like. To be honest with you, though, I just didn't like the name quite as much. I'll probably tweak it slightly.
The image attached is a Moabite stelae extoling the virtues of Chemosh, by the way. Not that I expect anyone to read it.
