Harlequin was an adventurer who founded the modern Occultists guild. He went down in history as the first mortal in the Modern Age to be slain by another when he fell by the blade of the founder of the Templars, Sir Gawain.
Harlequin is perhaps most famously remembered, however, for being the subject of the first Logosian decree by Sarapis on an early public news posting: "There will be NO molesting of the sheep. This means you Harlequin."
