James Marchwood

Lord James Marchwood was the owner of Ashen Hill Manor in the south of England. He employed Erasmus Darkening, as Eramus said he could make gold. After his children went missing he went looking for them. Marchwood found Darkening and asked him about them, but then stabbed him and his machine with his sword. He later vanished like his children.

In the early 21st century his "ghost" manifested to defend Sarah Jane Smith from a red-eyed creature. He then vanished.

Following Darkening's defeat he was reunited with his children in the next life. Their actual ghosts are seen by Sarah Jane as she leaves the manor. (SJA: The Eternity Trap)
