Dimmamar is an Imperial world in the Segmentum Obscurus, most famous for two things: the foundation of the Confederation of Light, and the birth of Sebastian Thor, who overthrew Goge Vandire and later became Ecclesiarch. It was also the first planet to defy the will of Vandire and declare him heretic.
In 858.M41, Dimmamar would come under sudden attack from the Eldar of Craftworld Ulthwé without any warning or apparent reason. Seraphim led by Seraphim Superior Amelda of the Order of the Bloody Rose from the Sisters of Battle retaliated in a daring attack, slaying the Eldar Farseer.[1]
The people of Dimmamar have had past dealings with Fabius Bile, who is known on that planet as "the Chem-master."[2]
