Nasaar Kol, the "Tower of Night", is a Dhakaani ruin in the northeast of Droaam, just north of Turakbar's Fist.
It was the site of a conflict between Cyran special forces, led by Greykell ir'Ryc, and the Order of the Emerald Claw led by Suradin ir'Taggert. The Karrns had managed to get the ruins open, but both parties were captured by the Znir Pact before they could venture inside.
The Znir Pact have stories of ghosts around the ruins. Lozaal Daashor believed that Nasaar Kol is the hidden vault of the Kech Nasaar, and this was proven to be correct when he visited the site in 106. Nasaar.
