What the who now? Missed that one, and I think I'm better for it.
God of the goblins.
My preference for a 4E core 'evil' pantheon would be, based on what's been revealed and hinted at:
Bane for the "LN/LE overlap" style of tyranny and militarism (confirmed in the Pantheon article--as is his role as common patron of hobgoblins)
Asmodeus for usurpation, unholy knowledge, and the pure 'sell your soul for power' diabolic evil (pretty much confirmed)
Gruumsh for evil barbarians and savages, including a lot of orcs (his presence is strongly hinted at in the Pantheons article; this is my concept for making him more than just an 'orc power')
Zehir for assassins, conspirators, poisoners and serpents (name mentioned in the Pantheon article, and Yuan-Ti Champion of Zehir in
Desert of Desolation; guesses based on those factoids)
Torog for trolls, ogres, evil fighters and wicked denizens of the wilderness (named in the Pantheon article; guess based on name)
Lolth for scheming, drow, and other Unseelie fey (guess based on Corellon info in Pantheons article)
Nerull for necromancers and undead (guess based on need to fill the niche and iconic stature)
Tiamat for greed, betrayal, and evil dragonkind (presence a guess based on Bahamut's presence in the core pantheon; portfolio is just my own reimaginings for making her more than just a 'devil overlap'.)
Honorable mention to Orcus and Demogorgon as not quite Powers but possessed of cultists and possibly spellcasting clerics.
EDIT: Oops--forgot one. Tharizdun for entropy, madness, and elemental evil. (Presence in the mythology confirmed in the Demons & Devils article)
