Iax

Iax is located in the Ultima Segmentum, within the Ultramarines Empire of Ultramar. It is an Agri World, and is sometimes known as the Garden of Ultramar. Its climate and fertility have made it one of the most productive worlds in the Imperium.

There are no large cities or Hives on Iax, its land given over to producing quality food. The oldest and most densly occupied region is the ancient fortress city of First Landing, where the residents of the planet flock to in times of desperate need. It has been a scene of many raids over the years, but it has always survived and returned to an unusually high degree of fertility.
