Valonia

"We failed to our duty. Our world has been wipped out by these foul aliens. But we will avenge our world! We will purged the Galaxy of their taint! For the Omnissiah!"

- Omni-Master Vlad Malenkov

Valonia was a very technologically developed Hive World which have the particularity to follow the Cult Mechanicus, the official religion of the Adeptus Mechanicus, rather the the Imperial Cult of the Adeptus Ministorum, which lead to tension between the planet leaders and the Ecclesiarchy.

In the late M36, the planet has been attacked by an undetermined Tyranid Hive Fleet, and is now a Dead World covered only with the ruins of the mighty hives that have existed long ago.

History
Valonia has been colonized by the Imperium during the Great Crusade but very little informations from this period has come to us. All we know is the t it was a very prosperous world until it was attacked by the Traitor Legions, and turned into a giant desert with only its mineral ressources left.

Birth of the Omniscions
In the 36th millenium, the Administratum allow the creation of a Space Marine Chapter from the planet, based on the genetic heritage of Ferrus Manus. The people of the planet being fierce devout of the Machine God and sharing the same contempt for human flesh.

Tyranid Destruction
In the late M36, an unidentified Tyranid Hive Fleet launch an assault on the planet. Unfortunately, the bulk of the Chapter was at the other side of the Milky Way and the planet didn't have enough defence against the Xenos and tehir worshippers.

After many months of war, the invaders finally won. And the Omniscions only found a Dead World when they arrived.
