House of Wolves
With the Hive forced back from Earth, the power struggles between the various alien forces have shifted. Capitalizing on this, a mysterious group only known as the Nine break a mighty Fallen Kell (leader) out from a prison deep in The Reef. The leader of the House of Wolves, Skolas, believes that he will be the Fallen ruler to unite all of the different houses and become Kell of Kells. In a desperate effort to contain these Fallen pirates, Mara Sov invites all Guardians to her outpost in The Reef, allowing her chosen embassies Variks the Loyal and Petra Venj to guide our Guardian to Skolas and his pirate army.
First sent to Venus, the Guardian fails in stopping Skolas from gaining support with the House of Winter. Fortunately, things on Earth are much more successful, with both the House of Kings and the House of Devils prevented from allying themselves with Skolas. Skolas is then tracked down to the mysterious Vex stronghold the Vault of Glass, where him and his barons are attempting to steal their time-altering technology. After fighting through waves of Fallen enemies, the Guardian traps Skolas on top of a spire above Venus. Skolas is weakened enough for Petra to capture him and transport him to Variks’ Prison of Elders.
Even after Skolas’ defeat, Petra assigns the Guardian to hunt down the remaining barons and generals that escaped capture during the attack on Venus. Variks also offers three Guardians the chance to enter his area known as the Prison of Elders and execute Skolas once and for all.
