I want to stat them, cause I like statting gods
. But I can't figure out how to go about it. I was thinking more along the lines of 40 class levels each, DvR 1 (or its equivalent, that can be worked out later), and of course, dominion over the weather of Arcadia, plus some special powers relating to the weather immediately outside their citadels.Does anyone take issue with the seemingly contradictory description of them in Planes of Law? They are said to be demipowers in their own right, and furthermore are supposed to be invincible within their domains. Yet, they're given regular stats, and are described as simply humans. Is there any other source of information about these mysterious (once)mortal beings?
All gods were invincible in their own domains in 2e, so that's not really a contradiction. If you don't like playing it that way, ignore that bit.
The Storm Kings were like Primus in that their powers only existed while they were in their realms; if a Storm King was to leave his throne in Arcadia, he would be an ordinary human (or whatever race he was - there is a half-elf Storm King and a tiefling Storm King) again. That is, their divine ranks and attendant salient abilities are a property of their station, not of the Kings themselves. The role of Storm King does not grant its inheritor with immortality; the King continues to age as a mortal would.
How many class levels they have isn't fixed, and won't correspond with their power level; when one King is replaced by another, the new King keeps whatever class levels he or she had before, and adds on the various divine powers for as long as he or she keeps the job. When the old King dies, a new one is chosen (I assume some sort of series epic tasks are in order, testing more the character's lawful alignment, judgement, and fairness than physical or magical ability, and in the end the plane itself recognizes the competitor who is most worthy). Some Kings might be high-level characters, others might be mid-level commoners (Planes of Law said they have to be at least tenth level).
"Storm King" is more a template that can be applied to anyone than four distinct individuals.
This thread in the Umbrasa Gravelands describes a few of the Storm Kings in greater detail. Of course, that link's just Brain-box's view; it's interesting, but not necessarily canonical.
