OK, I'm thinking of odd and complex, but I think the backstory works for what I understand of Strange Aeons...
Bexer Bonn, a young man hearing voices.
Crunch is a Synthesist Summoner/Bladebound-Spellblade Magus (Assuming the very class set doesn't actually set off a stroke, I can begin working on the crunchy bits.)
The short version of this is a young boy who was bonded with a piece of Numerian technology that manifests as a suit of baroque armor that whispers in his head. At level two he'll suddenly be manifesting a force blade in his off-hand, and at level three he'll find himself in sudden possession of an arcane sword that also tells him to do things...
That all ended in Bexerian's 12th year. During negotiations with the court of the Black Sovereign in Starfall, the Baron's suite was attacked by one of Numeria's Gearsmen. The Baron and Baroness were killed instantly, and Bexerian barely escaped, running in terror from the pursuing Gearsman.
His memories of the chase are faint, ending with him falling through a doorway in one of the corridors of Silvermount. There, in a room full of tiny flashing lights, he saw a strange device hanging within a column of light. His last memory was of a voice speaking in a strange language, and then darkness.
When Bexerian awoke, the room was dark but for a fading glow, by which he could see that the device had been implanted in his chest, only a small metal disc and a silvery squiggle showing. Confused, he struck at the device (which a voice in his mind called the 'Cyclo-Heart'). There was a sense of metal encasing him, and again he blacked out, awakening three days and fifty miles later.
Since then, Bexerian (now calling himself Bexer) can barely remember the last several years, except for images of the strange metal armor that encases him, and speaks in his head in a strange, cold voice, filling his head with things he can't possibly know.
