Dagon father Darth Molock was a secret apprentice of Jorak Uln who scaped the wrath of the Sith Mekel and retrained jedi Revan (formerly Darth Revan) there he escaped with his only son Dagon to hide in the tombs of Korriban.Darth Molock was as Twisted and evil as his former master Jorak Uln and start making experiments trying to create the ultimate sith.Jorack Uln teach Moloch the art of Sith alchemy and how to channel the dark force to his will.Molock knew that in the times of the Dark Lords they create powerful monsters, one of those monster we the so call Leviathans who had the ability to absorb the life engergy and knowledge from their victims.

Then in his Twisted mind Molock start experimenting with the fellow acolytes that korriban send to their trails.Many acolytes die on the trials of Korriban. if was the perfect place for Molochs experimentsYears and years passed and every subject die. none of the acolytes were strong enough in the force to resist the experiments.But then. in his evil and twisted mind he saw his son Dagon strong in the force.Months passes and the experiment was complete,Dagon resisted the process and become a humanoid-Leviathan with the ability to absorb the life energy and knowledge of their victims.But Molock notice something his son not just gain the leviathans power but their weakness."No matter he is ready" Moloch say with a calm voice. Then Dagon was send to Korriban to begin his training as a sith.

Dagon was unaware of what he was, but knew ,he could do something no other Sith could do he could sometimes literally remove someone's memories and make them his own. but was very susceptible to Force Lightning. During a particularly grueling trial set forth by his Overseer, Eteavua, he returned virtually unscathed. He had been sent out into the desert of Korriban for a week with very little water and was expected to survive for five days while fending off and defeating other Acolytes who wanted to see him fail...yet his nutrition levels never decreased, his throat and lips were never parched, he seemed to be thriving out there, his skin wasn't even burned from the sun's rays....this raised many questions: was he even human at all? Overseer Eteavua, a female Sith Pureblood whose family were a long line of archivists, recognized some of his characteristics, and investigated to make sure. She went to the site where his trial was held and after some digging, found the bodies of several dead Acolytes, they were all dessicated as if they had been drained completely of their life force. With a growing suspicion of what was going on, Eteavua who was a close personal friend of Darth Mortifera, recommended Dagon to be transferred to the Sith Academy of Yavin IV in an attempt to prevent him from being discovered by any of the Sith Alchemists on Korriban who might want to dissect and study him if they ever found out.

Perhaps the Yavin IV Academy could help him in ways that Korriban could not.
