Behind the scenes

 * His name is pronounced "TEST-uh-cleez", rather than "TEST-uh-kullz" as some may think at first glance.
 * His name is a reference to a debug character featured in another Black Isle/Obsidian game, Planescape: Torment.
 * In Van Buren, there is a character named Testocles who simply berates the Prisoner, who could be countered using a skill above 5.
