History
Islington was the protector of Atlantis. While it claimed to feel sorrow for its destruction, it is later revealed that it destroyed Atlantis itself. Islington claimed that the people of Atlantis deserved it.

For its crime, Islington was imprisoned in London Below, and the key to its prison was guarded by the Black Friars.

The Present
Islington hired two assassins, Mr. Croup and Mr. Vandemar, to kill Portico and his family. It had the duo write in Portico's diary that Islington was a friend and should be trusted. Portico's daughter, Door, read this and sought out Islington along with her companion Richard Mayhew. Islington told them that if they retrieved the key, it could solve their problems. As Door and Richard went after the key, Islington instructed Croup and Vandemar not to kill them.

When Door and Richard retrieved the key, Islington had Croup and Vandemar capture them. It revealed that it needed Door to use the key to escape its prison and create a portal to Heaven. Islington planned to invade Heaven and overthrow God and the other angels. When Door refused to comply, Islington had Richard tortured in front of her. Door agreed to open the Door, but revealed that she had the key replaced, and she opened a door across space and time. Islington, along with Croup and Vandemar, was sucked through the portal and trapped.
