Oksphyra

Oksphyra is a gargantuan amorphous ancient beast whose body is made entirely of the corrosive substance, Devourite. Whenever it makes physical contact with an organic substance it consumes it (with exceptions only if Oksphyra wills them), and it can consume inorganic material if it wishes.

Originally from south of Bravitak, Oksphyra cut a channel to the east until it reached the Oshin Sea in southern Yidmark near the end of the Silent Era of Whirn because of the city being built nearby its original dwelling. The Arthosian Gnöbs later named this channel the Oksphyran Canal, and Oksphyra's original dwelling became known as the the Glass Crater because of the clear ice that fills it. Arthosians discovered trace amounts of Devourite under the ice and its properties were studied, but it could not be safely moved, so it was refrozen over the centuries.

Oksphyra continued cutting its path and turned north in Faravay, where it was bothered by Allium golems. Finally, it settled once it reached a spot in eastern Geh'b Yaqel where blistering desert met treacherous mountains, and life was uncommon once more. Here it stays in a chasm it cut for itself in the ground (Agrakarga's Abyss), waiting patiently for the end of days.
