Origin

The son of Albert Caldecott and great-grandson of Richard Swift, also known as the Shade, Dudley Caldecott was born and raised in England, probably London. It is unclear if he is a hereditary peer or a life peer; evidence seems to suggest hereditary. If so, he inherited the title and accompanying social position and power from his father upon his father's death. At some point he developed an inner circle of occultists and corrupt industrialists, becoming a leader of the vaguely-named "Group," and providing members with access to mysterious supernatural beings that had first been discovered by his father.

Creation

Dudley Caldecott was created by James Robinson and Frazer Irving.

When this fails he and St Aubrey formulate a new plan, orchestrating the capture and subduing of the Shade using their captive supernatural beings to cancel out his powers.
