Iron Myre was once one of the kingdoms of Minecraftia and was the last standing nation to Herobrine's attacks. Two cities are known: the city of Iron Port, where Herobrine burned everybody alive and turned the place into a boneyard, and the capital of Iron Myre, the name of which is unknown. It is believed by some that it was called Ironias, due to the fact that the cloth shop was named "Ironias Cloth Shop", however, this could just have been the name of the owner. A strange thing about Iron Myre is that the sun rarely ever rose in the land, not once in the year that Grayson was there alone. Another is that the blood of all the long dead citizens never dried away.

In The Haunted, Grayson's home is an old Iron Myrian castle.
