History of Skolas

Skolas was a Fallen Captain of the House of Wolves who became its Kell during the House's war with the Reef. He called himself Kell of Kells and sought to unite the Fallen Houses under his rule. He is the main antagonist of the House of Wolves expansion, which was released in 2015.

After Guardians defeated him at the Citadel, Queen Mara Sov ordered him returned to the Prison of Elders. In the Destiny 1 Prison of Elders, the level 35 challenge "Skolas's Revenge" ends with him as the final boss, armed with a Scorch Cannon and protected by two Kaliks Minor servitors.

In Destiny 2, Fikrul, the Fanatic of the Revenant Scorn resurrects him in the Revenant episode as "Skolas, Scorned Wolf", using the Echo of Riis. He is the final boss of Kell's Vengeance, a shorter variant of Contest of Elders for two to three players.
