Arathi Basin

The Highlands Rise · Original zone 5 of 12 · final boss Lord Aliden Perenolde

Zone 5 of 12 Opens: Defeat King Mosh in Un’Goro Crater Verified on v0.123.0

Checked against v0.123.0Updated October 26, 2026

With the Basin's banners down, the Highlands come for it: Boulderfist ogres and Witherbark trolls out of the hills, and the Syndicate behind them, sent by the last lord of Alterac to take it for his own. That is the zone's own intro, straight from the game (v0.123.0 build data) — and it names the power you are here to end: Lord Aliden Perenolde.

The boss lineup, in spawn order

Five bosses, verified from the game's build data. The starter zone's clock (3:00 Hogger, 6:00 Mother Fang, 9:00 Rhahk’Zor, 12:00 Mr. Smite — final Edwin VanCleef 16:00) shows how a chain run paces — per-boss minute marks for this zone are being verified in-game.
