A Dren spire-city on Isthavol's high plateau. 42 slender crystalline towers connected by aerial bridges. Cold, austere, proud. Home to the purest Dren traditions � and, recently, to Arbiter Thessiva Dren-Kaar's private laboratory.
Each Corthen tower is maintained by a single founding family line. The Dren-Kaar tower is the oldest and, for the last five years, sealed to outside visitors. Residents speak of a continuous low hum emanating from its upper floors at night.
