Variant Imps/Quasit

[Ruethgar]

I remember in I think a Dragon Magazine there were a handfull of variants for either Imps, Quasits or both. They exemplified different aspects of evil. I can't for the life of me find where they were though. Anyone have any idea?

Edit: Found what I was remembering, even if I was mis-remembering the content. Dragon Magazine #338 p32: Imps of Ill-Humor

[Thurbane]

There's also some variant Imps in the Fiend Folio (Bloodbag, Euphoric and Filth).

There's the Bog Imp in HoH, but that is not a true Imp, rather a type of fey.

There only appears to be the one type of Quasit, which is odd considering there tends to be a lot more variety in the ranks of Demons than Devils.
