An unidentified hexton was the proprietor of a shop in Sigil. This hexton modron was known for being the first builder of steel predators. When they were first constructed, they were seen as impressive, before the hexton turned the predators on his superiors, where they caused havoc, until the hexton responsible was captured and exiled.

It proceeded to procure a shop in Sigil, where it manufactured steel predators for hire.[1]
