Nyan Marmu

Nyan Marmu was an ancient Eldar palace built south of Ventinya into the flank of a mountainside. It was the second-to-last mansion in existence after Non Selpossis. It was famed for its elegant halls and lavish dining rooms, as well as seemingly endlessly deep caverns and mines. The Cellar of the King held a famed wealth of jewels, gold and priceless items.

At some point after the First Cataclysm, the Dragon known as Zulaxa the Black, attracted by the wealth within the mansion, slaughtered or drove out all of its residents and made a lair in the Cellar of the King. He was eventually driven out by Alutun Nolcastu in 4145.
