Mithrax, Kell of Light

"Wolves rebel. Now, Wolves extinct. This where-live mine-things scatter must end. I will Kell the mind-open Eliksni. No spider-tricks. No loyal-lies. Variisis truths. We fight for Great Machine together."

- Mithrax

Mithrax, the Forsaken is a former Captain of the House of Dusk who decided to ally with the Guardians of The Last City following an encounter with The Young Wolf. He is now the Kell of the House of Light.

Meeting with Sjur
At one point Mithrax, a Vandal, is chased by Sjur Eido. Later she befriends him as they exchange names and Misraaks becomes Mithrax and introduced to the Dreaming City. Sjur becomes so renowned among the Eliksni they called her Siyuriks pak Variisis "Sjur, the Unyielding" and forms an early alliance by giving Amethyst crystals as political gifts to Archons.

Titan Methane Reactor
Later Mithrax would leave his wolf-born house and join the House of Dusk. In the Enemy of My Enemy World Quest Guardians will encounter Mithrax and his crew as they both try to gain control over the reactor. Various Barricade Servitors and a High Servitor Selkis, the Obstructor are put in the way to prevent the Guardians from reaching the core. Mithrax can later seen dueling against a Hive Knight in which Guardians are given a choice in who to kill. Killing the Hive Knight and leaving Mithrax alive will activate an alternative ending in which he will speak in Fallen language presumably establishing an alliance with the Guardians. He disappears and grants the player access to the reactor.

Alliance with the Guardians
While not physically appearing in Forsaken, sparing him is revealed to be the canon choice, as he defects from the House of Dusk and swears allegiance to the Last City, eventually joining a fireteam of Guardians. He argues that humanity, not the Fallen, are befitting of the Traveler.
