Marion Hedgepeth

"Prince" Marion Hedgepeth is the son of Asmodeus, Lord of the Nine, and brother of Lady Glasya, Lady of the Sixth. As of several years ago, he was the proprietor of the Lower Plane, a bar in Sigil's Lower Ward.

As proprietor of the Lower Plane, he offered a safe location for fiends of all stripes to meet and discuss deals and alliances. He was an associate of Orihara's, often allowing him to operate out of a private room in the back. He was also a well-known planeswalker.

A year ago he went back to Baator, and was given a large army for an unknown purpose. This occurred immediately after he left Sigil, which occurred after Tripps Contracting recovered the Book of Vile Darkness for Orihara. 

Most recently seen in Oerth, when a strike force funded by Mephistopheles disrupted his plans there.
