Corru

Corru is an organometallic material composed of 'essential metals', one of which being copper. It is a living organism that is grown and shaped by corrucystic engineers through methods that are currently unclear.

Black corru
Black corru is a structural variant of corru that forms naturally in spires. It is black in colour with a purple sheen, and possesses far higher density and strength than normal corru.

Corrucysts
Corru naturally grows into spheres called corrucysts, which form a hard outer layer of glass that parts for Obesk receptors, allowing the corru within to be taught how to function.

Corrucystic hardware forms the backbone of Obesk technology; their development sparked a revolution that rapidly spread across Obeski, and paved the way for the construction of the Okizika and the unification that followed.
