AFAIK he was (iRP) a lunatic who went all over Sirius in his cruiser thing, the Necrosis, torturing and killing his way across the sector with a little AI sidekick thing called PSI Borg, which I think flew a Corsair gunboat back when it was a brown lunchbox.
Anyway, he (can't remember his name, but I remember the jumping elephant avatar!) did a metric ton of RP to get his Terrorist ID and custom ship. I only ever ran into the Necrosis a couple of times, once on my Harvester and once when I was trading, I think. Both were suitably chilling experiences.
