Geras

Geras is a creature who claims to be a Great Being. He is the creator of Nox.

Biography
The being known as Geras first appeared in the Matoran Universe shortly after the fall of the League of Six Kingdoms, claiming to be a Great Being and using his immense powers as 'proof'. Many Matoran swore themselves into servitude, fully believing his claims, and the majority of these Matoran were never seen again.

He then disappeared from history, along with all of his Matoran followers, though the Hand of Artahka and later the Order of Mata Nui did their best to keep tabs on his whereabouts and actions. When he began planning the creation of the blade Nox, the Order of Mata Nui created the Toa Rhodan and sent them to intervene. Geras turned all six Toa to stone and, after three weeks of intense meditation, he managed to bring Nox into being.

Geras then disappeared from his lair on that unnamed island, and has not been seen since.

Abilities and Traits
Geras possesses legendary powers, able to manipulate most of the elements in some form or another. He also appears to be able to create matter out of nothing, though it takes time and complete focus to create the desired object. Geras can also transmute one material into another, as displayed when he turned the Toa Rhodan to stone with a flick of his wrist.

His most potent ability is to age a target into oblivion, by aging them so far in such a short space of time that not only do they reach the end of their lifespan, but their remains corrode and decompose almost instantly.

He is known to wear long cloaks and robes, as many accounts of the Great Beings corroborate that they too wore clothes.

Mask and Tools
Geras wears a powerless copper Hau, purely for its symbolic importance. He often carries a blade staff, though he does not need it for combat, as the wave of a hand can destroy an enemy.
