Okay, guys, I've been trying to stay out of the whole alignment debate, but I'm getting a bit tired of seeing people disparage the efforts of writers and developers whom I respect a great deal. So I'm going to point something out.
The avatars presented in Strange Lands are, with the exception of Jandaveos, specific to Asherak. These are how the various demi-gods/lesser gods manifest on that continent.
Go back and look at Campaign Setting: Termana. It was in that book that we introduced the notion that the gods are worshipped differently--and even manifest/act differently--in different cultures. The same holds true of Asherak. In Ghelspad, Nemorga is a single deity. In Asheraki religion, "the Ne Morga" is a tri-partite entity, three related demigods. Otossal is one of them, and the Asheraki view of Otossal is chaotic.
