Crazy shit.
The Shrine of Ula-Tek was a massive structure in Zul'Aman that was the epicentre of Amani religion. It was a place where the barrier between the spirit realm and the mortal realm was especially thin.
After the death of Gruc'jen, it was given the additional name of Zul'Gruc'jen by the Amani of the Lebenstraum.
