Zat-Ylorackh

Zat-Ylorackh was a great and powerful fortress-city built in Tamaluk during the second age. It would eventually come to be a rival power to the city of Seraphis, but would fall into ruin under the cruel rulership of Califess Hulotala, a sorceress and necromancer who reduced the citizens of the citadel to legions of mindless undead servants.
When the arts of magic were introduced to the solfar who ruled the desert kingdoms during the Second Era, several califzar fell into the temptations of the profane paths. These old kings, seeking ultimate power within a strictly matriarchal society, rallied behind the banners of Hulotala, who led them to build cults to their own honour within their sandstone keeps. Enacting blasphemous rites forbidden by the ancient trolls, the fey raised their servants from their tombs and rendered them slaves even in death.
The holds of these fallen rulers were eventually brought beneath the sands by the armies of Seraphis itself, who enlisted the aid of verethran dragons and legions of ameret cleansers in their march against the unliving cities. This crusade would cleanse the stain of forbidden magic from the solfar homeland. When it became clear that their undead puppets could no longer hold back the blades and ritual magics of the righteous, many of the evil califzar sealed themselves in great stone catacombs, commanding their broken worshippers to commit ritual mass suicide in order that dark forces make their masters koschei.
it is thought that the kings of old still slumber within their sarcophagi, wrapped in the mouldering wrappings which held etched upon them the tartarian symbols that granted the sorcerers eternal life. beneath the shifting sands of the endless desert, the ancient stone cities still lie, untouched for countless cycles. It is best that they remain undisturbed.
