Destruction is the fourth eldest of the Endless. To the ancient Greeks, he was known as Olethros. When the universe began, he was formed as the anthropomorphic personification of destruction and creation. He is the only one of the Endless to abandon his realm and responsibilities, and so his siblings often referred to him as The Prodigal. His realm, now abandoned, is known as The Fulcrum, which exists in a constant state of mid-explosion and is empty, except for a large black sword.[1] Since he abandoned his realm, the galleries of his siblings have a blank place where his sigil, a sword, once was.[2] In his travels, he was accompanied by a talking dog, Barnabas. Barnabas was later given to his sister, Delirium.
