Well back on the rails...
If Grief made Moor Elves, were the other races in Altera made from specific gods as well?
Queen Grief wasn't a god- she was an Immortal King that corrupted already existing elves into something entirely different.
Once I heard (I can't remember if IC or OOC) that Jishrim made the humans. The elves had long lives to grant them wisdom to learn from their mistakes, but the humans had such short existences that they kept repeating their mistakes and sowing more seeds of chaos.
Theodra made elves I think.
(I am like 40% certain the above information. That is not a high enough percentage to take that as canon.)
I can clarify! Theodra gave the Forest Elves their traits while Sallana gave the Silver Elves theirs. Queen Grief corrupted those elves until they were unrecognizable.
Korog built the Dwarves from the first stone. Sallana made the Syrie, beautiful much like she made the Silver Elves. Jishrim did the humans. Jax had Halflings, but thats disputed in mythos. Shalherana created the Caparii to protect her forests from Jishrim's humans. Greylings, Nakam, and Earthspawn are wild cards.
(This is the old Fitz lore, very slightly not really modified)
Edit: Greylings were engineered directly by Queen Grief to serve as general minions - No one knows what existing creatures she used for them, if any creatures at all (Some argue they're corrupted halflings, other think they were once elves like the DarkElves^tm). While they were initially spawned from all of the Immortal Queen's repitoire of really-bad-things (hate, rage, evil, blah blah blah) - With the Final War and ending of Her influence they, along with Earthspawn and Moor Elves, lost these artificially terrible qualities and calmed down a little.
Due to their cunning, extreme magical aptitude, and the power of Queen Grief - Greylings molded Earthspawn from human sacrifice and the remains of Giants, among other foul and horrible things. The Earthspawn were promptly enslaved by Greylings, and used as brute strength and muscle - Being as physically capable as they lacked intelligence (dark magic isn't very kind to you). They didn't remain slaves for long (something something 'the problem with enslaving a race thats bigger and stronger than you is that they are bigger and stronger than you' -Fitz 2012)
Nakam came from seemingly nowhere, entirely off an island with a mysteriously magical core. The island somehow followed the Alteran people through Exodi, ending up in new worlds with entirely new oceans, without the native population noticing, which suggests it had world-hopping abilities. Either way, those stories are long lost, by now, as Kavdek was destroyed... Or vanished.
Some tidbits hidden in the Nakam lore alluded to this (specifically the 'southern mountains, from which visitors do not return').
