Iron Thanes
From Age of Sigmar - Lexicanum
The Iron Thanes are a Stormhost of Stormcast Eternals who defend Skyheld, a city of the Dominion of Sigmar found in the Ramhut's Spine of Bjarl.[1a]
Warfare
The Iron Thanes prefer to use tactics reminiscent of persistence hunting. They will lure the foes of Skyheld high into the mountains, into the path of blizzards, and through treacherous ice-fields, descending upon their prey when they are exhausted and half-frozen.[1]
