A towering city of gold, Taj-Nar, the Ancient Den, was the city and refuge of the leonin on Mirrodin. It was here that the leonin kha, or king, resided.
Taj-Nar was visited by Glissa Sunseeker of the Tangle, who unwittingly brought Memnarch's forces to attack the city while searching for her. Glissa left the city soon after the death of Rishan, daughter of the seer Ushanti. The city was later destroyed by a mana bomb, supposedly by the kha, Raksha Golden Cub, himself. However, Vektro, a creature that could inhabit living beings, stole the identity of Glissa's sister, Lyese, and was the true culprit in the city's destruction.
