Mken 'Scre'ah'ben (Earth-5875)

Mken 'Scre'ah'ben was a Reformist san'shyuum High Lord and first Hierarch of the Covenant, who founded the empire and signed the Writ of Union alongside the sangheili leader Pelahsar the Strident.

Biography
After the War of Beginnings had waged for years and claimed thousands of lives, the technological superiority of the san'shyuum with the Dreadnought proved too much for the sangheili, so much that they needed to revise their traditions of not tampering with forerunner technology to save their colonies and escape from extinction. Both species eventually agreed to settle for peace and the war was deemed a stalemate. In 852 BCE, High Lord Mken 'Scre'ah'ben sought a "tentative truce" with the sangheili, meeting with the leader Pelahsar the Strident in Sanghelios. There, both leaders forgave the past crimes of each side and signed the Writ of Union, forming the alliance that became known as the Covenant.
