The position of Ms Grey is an important one in the demonic hierarchy. A senior tempter committed to the material world as a diplomat, spy, and insinuator.
Moira doesn’t know what Ms Grey’s actual name is, she’s never asked. This is hardly the strangest thing about their relationship: Ms Grey is the demon who consigned Moira to her unending existence on the mortal plane. Sometimes flirtatious, sometimes resentful, sometimes cold with anger, the pair carry out an on-again-off-again romance for reasons that are difficult for either of their friends to grasp. It’s not even like the sex is good, Moira can’t do that sort of thing any more.
Ms Grey moves in refined circles. She attends the best parties, a scandalous presence for the well-to-do to gossip about.
