Halston Montil
Halston Montil was a member of the Royal Guard, serving under Geoffrey until he was assigned to take on the Followers of Armageddon (effectively the career-making "big case").
He first came to prominence helping Trinsic fight off Elementals, in an attack that later was shown to be a distraction for the Followers of Armageddon.
It seems to be unknown what happened to him following the conclusion of his "big case."
