Stifford Coll is an older man who retired to hermitage in Pfenniger Forest. He calls his abode Thurrok, and has a dog named Mardyke.
In his previous life he was an engineer who worked for InTech, and was then one of the founding members of the Frumentarii which was formed in the early days of Calydon.
He maintains a tenuous cease-fire relationship with the Reapers, while the Fallacy Fairies leave him well alone. This is in large part due to his automated A13-RG, the Fail Gun.
Stifford stops in Tin Can Central periodically to buy goods. He is a skilled Mechanic, and was also involved in some of the late-design Gravtrains. Occasionally wealthy outsiders or the Humanists of Sebastapol will requisition his skill for specific constructions or operations.
His name is based on astronomer Clifford Stoll. Also see Vince Coleman.
