Before the Haunting 3Edit
The book said that the army was burned alive along with the entire city.
The Haunting 3Edit
It was the first place in the Badlands Drake, Armen and Grayson succeeded to get to, and appears to have been transformed into a complete boneyard. Grayson even set up a temporary home inside one of the ruined buildings, with a campfire and a shelter for him to sleep in.
Iron Port has not been seen since Grayson took Drake and Armen to the capital of Iron Mere, where they had their final comfrontation with Herobrine in the Haunting 3.
