The Sunreaver Onslaught is the Horde reputation faction introduced in Patch 5.2. It is personally led by Lor'themar Theron, Regent Lord of Quel'Thalas, and bears the namesake of the Sunreavers. Its base camp is named the Dawnseeker Promontory.
The onslaught will face off against the Kirin Tor Offensive to lay claim to Emperor Lei Shen's island stronghold and the treasures contained therein.
Daily quests for the Sunreaver Onslaught are divided into two categories, only one of which can be chosen per day: PvE-oriented tasks, or PvP-based missions. The former involves assisting Grand Magister Rommath, Halduron Brightwing and Aethas Sunreaver in dealing with the local threats (primarily the saurok, the Zandalari and the mogu), while the latter is focused on attacking the Kirin Tor forces and defending the promontory.
Outcast from Dalaran, the Sunreaver Onslaught fight to obtain powerful mogu artifacts from among the ruins of Thunder Isle, and to secure their future if the Horde falls to anarchy.
The Sunreaver Onslaught combines elements of each major hallmark of the Thalassian military: Magi (under both the Magisters and the Sunreavers) comprise the bulk of its forces, and are supplemented by rangers, Blood Knights and Spellbreakers.
Arcane golems and powerful mana wyrms are also on hand, along with agents of the Reliquary.
