Arcane Golem (Stormwind City)

Arcane Golems are arcane golems located throughout the Wizard's Sanctum in the Mage Quarter of Stormwind City, apparently serving as guards for the new portal room.

Speculation
As the Wizard's Sanctum bears the insignia of the Kirin Tor, and as they have used arcane golems before in their settlements, such as the Arcane Destroyer and Kirin Tor Constructs by the Kirin Tor Offensive at Violet Rise, it is possible that they were the ones who constructed and provided the arcane golems.
