Yirksii

"Kill a Grimm, I claim it as Scorn. Kill a Scorn, I raise ten more!"

- Yirksii

Yirksii, also known as Riven's Pet and "Big Ugly" by Arc Squad and formerly known as Yirksii, the General, is an undead Korman who had been resurrected by Riven with One Thousand Voices, and later being given the weapon.

In his previous life, he was one of the Korman's most respected and effective War Generals, being generally more favoured by the Emperor. Due to this, he unofficially became the War Commander of the entire Korman military forces, ranking directly under the Emperor himself. After the Great Fall of 2043, Yirksii discovered that the Eclipse Empire held a vital research facility on Europa, a moon orbiting Jupiter. In an attempt to destroy this facility and cripple the Eclipse Empire's ability to develop super soldiers, he led an attack on the moon. However, he was killed by Arc Squad after boarding the Eclipse Naval Command flagship the ENSS Headmaster.

A few months after being killed and his body on the surface of Europa, Yirksii was resurrected by Riven with an ancient weapon of Darkness and immediately recognized her as the one who has always led him. After this resurrection, he held no memory of his past life as a War Commander and attacked the Ravenclaw Blacksite, killing every single person within it and leaving the facility in ashes. Afterwards, he began to follow the orders given by Riven, traveling around the galaxy to build a Scorn.

Introduced as part of The Blind Well content update for Call of Duty: Age of Extinction, Yirksii serves as the final boss of "Rose Squad: Oracle Engine" and is mentioned numerously in the Blind Well activity by Riven.
