Sossal is a distant realm north-east of the Great Glacier.
It is described in just a few paragraphs in AD&D 2nd's The Horde and the Grand Tour of the Realms and seemingly completely ignored in the 3.5e sourcebooks.
The wiki is also very anemic, and mostly mimics what is already in those two books.
I'm not much interested in crunch, only fluff (what?) is enough.
Is there any source material on that realm (beyond what is described in the ones above)?
