Celestionic Sector

"Sir, we've lost all communications! Shields are down!"- an unknown Imperial Navy officer to her Captain whilst moving through the Celestionic Warp anomalyThe Celestionic Sector is located in the Ultima Segmentum, in the northern reaches of it. This sector houses the Celestial Hawks, Preachers, and Artic Foxes Space Marine Chapters. It also houses Celestion, the sector capital, which produces the Celestial Guard Imperial Guard Regiments.

This sector is surrounded by a massive warp anomaly, almost cutting off communication. It is known as the Celestionic Barrier. This anomaly almost cloaks the sector, making it almost invisible to all, but psykers. There is only one way to get in and out of the sector (pictured above) and that way is guarded by the Fortress World Celesta and it's many Imperial Guard regiments.

Founding
This sector was first colonised by Imperial colonists during the early days of the Great Crusade. They came upon a sector rich in minerals and planets and were quick to settle. They erected huge Hive Cities on those worlds they could and built mining worlds on the others. They named the sector after their greatest planet, Celestion. Soon the Mechanicus took interest in this sector after several artefacts were found. They created multiple Forge Worlds and outposts in the hopes of making this their sector. However, the Horus Heresy stopped that.

The Heresy
When the Ruinstorm was conjured in the Ultima Segmentum, Celestionic was enveloped by a massive storm of their own, surrounding them and trapping them in. The people of the sector boldly fought back and began to chart a way out. Seven years after the Great Scouring ended, the first charters made it out. As they had been on their own for so long, they wished for none of the help that many others wanted to offer. Instead they remained independent and forged their own legacy.
