The memoriam crystal z11 is found on Freneskae. It is one of twelve Memoriam crystals needed to unlock the Helm of Zaros cosmetic override.
The lower planes once more bear fruit. One race, the Ilujanka, has joined my empire on proviso that I solve their infertility. This seems like a problem worth solving. I am only capable of reshaping existing forms of life: to solve an issue of creation will require something more. To this end, I have returned to the place of my birth. With Freneskae's failing anima, Mah has slipped into a coma. She manifests nightmare creatures from which I am able to harvest her elder energy. I have pushed the limits of my own abilities, reforming the essence of other races into new beings... but to give them life required Mah's energy. As such, they are a failure, only proving of what I am incapable. Strictly, they should be named zarytes, but I have dubbed them 'nihil', for they are nothing to me. Much like the Mahjarrat, they have the ability to absorb the essence of their brethren. One of these nihil - originally shunned - has fast outgrown the rest. I have chosen to uplift her. To do so, I had to implant a small sliver of my being. The irony of this is not lost on me. I am not proud of this, but to leave her as she was would have seen the other nihil destroy her. With her newfound sentience, she has named herself Nex in the old Infernal tongue. Her speed and capability for learning are astounding. Although Nex will prove useful in bringing unity to the world, this entire experiment has only gone to prove my unworthiness. I myself must take a new path and find a way to transcend to elder godhood, for only then will I be able to aid the Ilujanka, to create life from nothing.
