Basic Info

Iax is the "Garden of Ultramar", part of the Ultramarines realm of Ultramar. It is an Agri World whose climate and fertility have made it one of the most productive worlds in the Imperium.

There are no large cities on Iax, its land given over to producing quality food. The oldest and most urbanised area is the ancient fortress city of First Landing, its tall citadel withstanding the barrages of invaders over the centuries.
