Sea of Moving Ice

The Sea of Moving Ice was the northernmost place in known Faerûn. Almost completely uncharted, it was filled with icebergs and isles of ice, set wide enough apart for a ship to pass. The ice of the sea changed so that all but the most experienced seafarers could be caught off guard, proof of such are a collection of ancient ice-locked ships.

Inhabitants
Along with seals, walruses and polar bears, the Sea of Moving Ice was also home to other dangers. Lairs of ice trolls could be found in errant shipwrecks and white dragons often made home within larger icebergs.

Portals
A portal on the Sea of Moving Ice led to the High Ice.
