Ullanor Sector

The Ullanor Sector is the Segmentum Solar cube around Ullanor, the Ork capital the Emperor and Horus broke in the Ullanor Crusade and the Beast later used as a throne.

Ullanor-system, Cesstium, Nalkari, New Mitama, and Truan IX share the chart. Some later histories even claim Armageddon is Ullanor relocated after the War of the Beast.

The Ullanor Sector still matters as the Crusade's most famous greenskin prize. Unofficial maps keep the Solar parent and leave Ullanor under ullanor-system rather than merging it into Armageddon.
