Return of the Forsworn

History
"Those that have been wronged have returned. Those that once served will no longer be bound by tyrants. Those that have lost their home will take yours. Those that were once Marines of the False Emperor, are now the Forsworn. Those that have been betrayed will become great, your worlds burned, your people butchered, your idols defiled, your corpses giving way for more worthy life, insects. Slaanesh will have your death immaculate, we will provide."

- Vox transmission from the Forsworn, received by Battlefleet Tempestus Command, 321.M36

When the Imperial Navy became aware that an alarming number of ships disappearing throughout the Chiros Sector, a Fleet was sent to patrol in force. But when the said fleet returned to Navy Command, only three ships returned, all heavily damaged. The crew of each ship was in a panicked and terrified state, wildly repeating that, "..a legion of ghosts have come to tear us apart." However, there was a singular command deck attendee was lucid enough to deliver a message to Navy Command.

And so the Forsworn continued to sow terror and fear among the Imperium's routes through Segmentum Tempestus, ambushing Imperial Navy vessels in vicious and short lived battles. At first, it was only at the behest of Kazrand that the Forsworn the crewmen of the ships taken were used in dark sacrifice to their chosen God. But when power began to flow into the Marines for their tribute, the feeling of empowerment made tenfold over the connection all brothers shared. And so bloodlust and the ecstasy of dedicating beautiful and artful slaughter to their new God, Slaanesh, set in, and the Forsworn were soon taken over with addiction to the service of the Ruinous Powers. Save for Arkann himself who solely tread the path of the traitor now for the power of reaching the mantle of joining his masters in the Warp.
