Obsidian Suns

The Cult of Obsidian Sun are an unconfirmed Chaos Warband of the Fallen Primarch, Magnus the Red, of the once Loyal 15th Legion "Thousand Sons". After the sundering of Prospero this chapter splintered off and roamed the warp until they stumbled upon Megiddio Prime, once a Death World in the Belatoran Sector. They immediately set to colonizing the world and claiming it for the Greater Chaos Daemon Shari'karuth and the the Chaos god Tzeentch. Shari'karuth Found them while travelling thru the warp and killed their initial leader Shamaah Keres and replaced him with the current Great Seer, Argos Velias. After settling themselves upon the world of Megiddio Prime they set about raiding unsuspecting worlds in real space and stealing various items of power. These items include The Eye of Ruination and the Scrolls of Sargoth, amoung others. They recently attacked and obtained a supposed doomsday device from the world of Pavonis IV. Alongside Death Guard and World Eaters warbands. This doomsday device was taken after three Maulerfiends, known as the Talons of the Great Seer, attacked and nearly slaughtered a Redemptor Dreadnought of the Pillars of the Emperor Chapter of Space marines as well as two full squads of Cadian Guard infantry.

The Obsidian suns are rumored to mostly employ squads of warpflamers alongside squads of Rubric Marines in all out decimation attacks after they have procured what they need. Scattered reports have been received of whole Hives being engulfed in warp flame. Slowly crumbling as hoards of Rubric Marines march out in perfect lockstep. Their Sorcerer overlords either marching alongside them or above them of cursed discs casting spells or chanting in a cursed daemon tongue. Bringing destruction and ruin to all who satand in their way.
