Colchis

Colchis is where the pod of the Primarch Lorgar Aurelian landed and then became the homeworld of the Word Bearers Legion. Colchis was a pretty big world before it was fucked by the Inquisition. It was around three times the size of Earth. The people who lived on this desert world lived almost exclusively in the big cities like the capital, Vharadesh known as the city of flowers.

History

Before Lorgar's pod crashed into a river and was found by Kor Phaeron, Colchis was a pretty advanced world. Though it then turned into a shitty Feudal World, the landscapes covered with ruins of factories and other signs of a prosperous world. Colchis was then controlled by a cult called 'The Covenant' which was the major religion at the time of Lorgar's crash landing. After Lorgar landed, he was raised as a loyal member of the Covenant before he saw Emp's golden-plated abs in his dreams and decided to destroy the Covenant and replace it with the worship of the coming God-Emperor. Big E then landed, giving Lorgar the Word Bearers after a month of celebrating.

Post Heresy

The big blue sons of Roboute Guilliman came across Colchis which at this point had became a pretty shitty place. So the Inquisition decided to bomb it with cyclone torpedoes until the ruined world to literally explode, its special geological structure causing a chain reaction, killing all of the humans which were barely clinging to life in a destroyed, post-heresy planet.
