It's not that, I've just always thought of Aldun as his angry form. :shrug:
It's not. It's his other personality. Having multiple perceptions in a world where believe and perceptions shape the world and gods do that. Hell, Shor, Shezarr, and Lorkhan are the same guy, different name, different views, and different aims yet hardly anyone disputes this. Also, Shezarr was a political move too, in order to curb a deity who is HIGHLY anti-mer, due to the time god.
If you ask me, too many people are attached to a [censored] political move.
