The memoriam crystal z10 is found on Freneskae. It is one of twelve Memoriam crystals needed to unlock the Helm of Zaros cosmetic override.
I have known she was here since I first arrived - my companion of old - but I can avoid her no longer. I need her help. I feared the effect we would have on each other, but it was far weaker than I remember, perhaps due to our time apart. Her time with Guthix has turned her head, and refuses to interfere with this world. It is all up to me. As such, I have seized control of a device from her that allows for near instantaneous travel throughout the universe, even between Gielinor and Freneskae, its two furthest points. I shall use this 'World Gate' to more quickly and easily explore creation, and to further my knowledge of magic and science. Perhaps there are mortal races left who might yet join my cause, on worlds I have previously overlooked. The Mahjarrat have taken over from the dwindling Chthonian dukes and my empire is now self-sustaining. My presence is rarely required and I now work behind the scenes.
The mortals under my rule accept my philosophies and spread them of their own accord.
