King of Kings
The Lamenters were an unfortunate Loyalist Chapter of Space Marines who went Renegade for a time and took part, on the losing side, in the Badab War.
The Lamenters were also players during the events on Scintilla in Hive Sibellus. They had come looking for their lost brother who the group had unknownly killed when dropping the archway on the Arastus Forums. They then pledged themselves to help clear out the terrorists and regain control of the “generator” assuming that these terrorists had been the ones to also kill their brothers. They had lost a great number of brothers in the retaking of the “generator” and had also said they would hold it until the group could bring reinforcements. The group though suspicious of the Marines decided to head back a little bit later, only to find the Lamenters setting up teleporters around a blood-drawn Chaos star. With the Sisters of Battle left over from the previous battle the group killed the remaining Marines without learning the Marines true goal.
