The Frostwall Mountains

Bordering The Savage Lands of Bulgaard from the Kingdoms of The Heartland. The Frostwall Mountains run from east to west with two great ranges of large groupings of mountains on either side. So named for two reasons. One, it borders Bulgaard from the rest of what is considered the Civilized World. And for the deep thickets and caps of ice and snow nearly overtaking them. Regardless of seasons. No colder wind in the world blows as cold as from the Frostwalls.
Ancient legends say that Tribes of Giants once danced in delight of their victories. And where their dancing feet fell, great mountains arose from the earth and reached high to the skies. But as ever. The truth of the matter, eludes all explaination.
