John Constantine; Chas [Charles Chandler]; Map; Mercury; Swamp Thing; Clarice Sackville; Marid; Albert Case (death)
Synopsis
If you want to know anything about the city of London, just ask the arch-mage named Map. Constantine does just that, but quickly realizes that Map is not in his right frame of mind. John does receive a shard of information: something about a once-banished race of beings who are planning on making a big come-back. Others may have similar information - such as Clarice and her business partner Marid, who is very determined to meet Constantine...and, oddly enough, Swamp Thing. Mercury and Swamp Thing continue their search for Abigail Arcane and enter the realm known as "The Rot".
