Frostland
From Syra D&D Wiki
The Frostland is an inhospitable frozen wasteland spanning the southern reaches of Syra. It's northern edge is a massive cliff, rising hundreds of feet high.
Only three settlements are known to exist in the Frostland: Doth'Candorun, where the drow are imprisoned; the Temple of the Warm Embrace, which is populated mostly by undead; and Tarth Moordra, a harsh training camp for battle mages.
