Troy

Troy is a clockmaker in Minoc in Ultima VI. The Avatar found Troy to be a small, spindly man, who was as exacting as the clocks he made. Troy prided himself in precision, and took great delight in the ticks and the tocks that his clocks produced. Troy also enjoyed playing chess, believing it was an excellent way to keep one's mind fit, and looked on with disdain at those he felt did not use their brains sufficiently. Troy told the Avatar that he designed the mechanical components for a model of the heavens designed by Ephemerides.

Trivia
The model of the heavens Troy talked about may well be the Orrery visited by the Avatar in Ultima VII.
