Kain Darkwind's Savage Tide
Fortress of Unknown Depths
The Fortress of Unknown Depths is a castle on the outskirts of Magepoint where the archmage Tenser makes his home. The fortress is at a conflux of magical power, and those within it can use the ambient energy to empower their spellcasting. It is well defended in the air by Bloodhawks that roost nearby and attack anyone that flies towards the castle and surrounded by a lake in which many sprites and dolphins make their home.
The fortress contains, in addition to the libraries, treasures, vaults, and living spaces of an archmage of Tenser’s power a number of unusual magical artifacts, including the Fountain of Fortune’s Folly, from which Katrina Islaran drank.
