This one is a week late for the Traveller Group challenge, but I still wanted to post it.
Trin Linc was the shadowy figure at the core of many and diverse puzzles and problems in a Traveller campaign I ran long ago. He was a Special Operative for Counter Espionage for the SuSag Megacorporation. One of very few full cyborg bodies with augmented human brain and nerve system, Linc was a field operative who specialized in digital system infiltration, as well as the more typical spy duties. His allegiance was to his Megacorp, and he was resourceful and inventive in carrying out his mission.
