House Armegedon
Before the Great Schism, not much is known about this unknown humanoid species outside of speculation and hearsay. Said to hail from a long destroyed planet in the Deep Core, a world known in basic as Armegedia, this species take on and derive their last name from it in remembrance. A near humanoid species in appearance, their only tell-tale differences are glowing eyes and silver hair atop their bronzed skin and strong sensitivity to the Force, traits that dominate genetics no matter what species they interbreed with. Outside of this, their history and truths are lost to the ages of time.
The Great Schism
The first recorded appearance of House Armegedon took place during the Great Schism where two brothers, Ojin and Tor Armegedon, were mentioned to have been a part of the Jedi Order until Tor Armegedon followed Xendor and Arden Lyn away from Ossus to Lettow. It is recorded that Ojin was forced to slay Tor at the Battle of Columus before he disappeared without a trace from recorded history.
The Second Great Schism
The next recorded appearance found in the Jedi Archives of House Armegedon takes place during the Hundred Year Darkness where a Jedi Master by the name of Scorpius Armegedon is noted as a highly decorated War Hero and Jedi High Council Member, as is his nephew, Sune Armegedon, a Jedi Knight who was present at the Battle of Corbos where the Dark Jedi were finally defeated. Another Armegedon, presumably Sune's sister or perhaps a cousin, was recorded amongst the defeated Exiles before their shipment to Korriban.
Great Hyperspace War
Two other Armegedons are recorded during the Great Hyperspace War. One is Lunus Armegedon, a Jedi Knight whom fell during the first Battle of Korriban and another is an unknown Armegedon overheard to be called Mjan, a Sith reported to have been spotted during the second Battle of Korriban - however, it's unknown as to whether or not this variant of the Armegedon Bloodline actually existed or if it was speculation that was recorded.
