From Warhammer - Age of Sigmar - Lexicanum
The Iron Horde is a Bloodbound warband led by Daemon Prince Balghor. These Khorne Bloodbound are merciless slaughterers who exalt Khorne with every life they take. They wear armor-coloured like dark steel.
- Riding on the back of a city-sized mechanical scorpion, they and their allies breached the Sanctified Stairs, slaughtering so many servants of Tzeentch that it rained blood for a month on the lands beneath.
- Under the command of the Daemon Prince Balghor they attacked the Blades of Dawn over the possession of the Hazereach Realmgate in the Symboline Paths and successfully defeated them.
