The memoriam crystal s02 is found on Freneskae. It is one of four Seren Memoriam crystals needed to unlock the Crest of Seren cosmetic override.
Whenever lucid, Mah cries out for Zaros. I do what I can to comfort her, but that is not much. What Zaros saw as her controlling us, I see as her protecting us... and now it is my turn to protect her. She sleeps more than anything these days, and her dreams manifest - they are pale imitations of Zaros and myself, their bodies not even formed entirely of crystal. They are a waste of what little energy she clings to. Perhaps I can find some way to return their power back to her, if only to keep her lucid. Some make pilgrimages up the volcano to Mah, calling themselves her children. I pose as her to warn them off. I intend to visit them in this guise. If they are so in awe of her, then they might sacrifice their own energy to restore her.
