Jona Omid
Jona Omid is a farm hand on the Larynn Colony.
From an exerpt from a report by Lt. Kevin Breeman to the counselling department of the USS Ronin:
Jona was born on Bajor. He left Bajor in his late teens to live at the Larynn Colony where life would be simpler. His mother was an extreme feminist who was probably used as a comfort woman during the Cardassian occupation of Bajor. She has a bit of a resentment / hatred toward men in general.
Jona lived with a man named Uncers on the Larynn Colony until an away team from the USS Independence-A came by and met him. Shortly after that he was abducted by a glowing orb. He was next seen on the USS Ronin's last mission. He'd been brainwashed by means of a mechanical fly capable of implanting thoughts into its victim's head (http://games.groups.yahoo.com/group/sb118-ronin/message/6276). He now has something like MPD as you suggested in your latest post. Part of him remembers being a farm hand working for Uncers but another part of him believes he was actually a soldier of the Vaudwaar people. The name Uncers figures in both 'stories' about himself. In the first story he vaguely remembers Uncers as the man whose family he lived with on Larynn. In the second life story Uncers is some kind of personal trainer / mentor who taught him combat skills.
Slowly the two clumps of memories have been merging a little to the point that Jona actually remembered a meditation session with Uncers (in his military life) in which he found himself drifting down into memories of his real self (http://games.groups.yahoo.com/group/sb118-ronin/message/6339) .
