In the Age of Legends, he was a senior Knight of the Crimson Spire of the City of Spires, Sereatha. It is often difficult to tell if he's telling the truth or a farfetched lie, such as when he said the Tunguska blast was him "attempting to whack the rock into orbit". Though capable of discussing any subject, and he often does so in a rambling manner difficult to follow, he usually reveals little, preferring people to discover for themselves. He believed himself too important to remain behind to protect Thayla from the Horrors. Harlequin is quick to anger, but quick to forgive, except in the case of his all-consuming rivalry with Ehran. He is quick-witted, but his jokes may depend on some enigmatic reference that few in the world would understand. Harlequin is temperamental, with his attitude, manner, philosophy, dress, and accent, all subject to change depending on his mood. He has painted himself this way since at least the Renaissance.
More frequently, it is full whiteface with diamonds over both eyes and a triangle over his mouth. Sometimes, it is a single diamond over one eye. Underneath the coat, he wears blue jeans, a cotton t-shirt, along with anaconda-skin cowboy boots. His usual manner of dress is a long black or brown leather coat, with lots of buttons on the lapel. He is average height for an elf, being a head shorter in height than Ehran. His left ear was cut off in his first duel with Ehran. His eyes are green, with gold flecks, but may change depending on his mood. Harlequin's hair is goldish-brown, but he usually dyes it red and keeps it tied in a ponytail. 6.1 Harlequin used in a game mechanics example.He resides at the Château d'If, off the coast of France. Under his older Matrix handle of "-H-", he once posted an ominous message about wraiths. He fully believes that people should find out the truth for themselves and never by merely accepting what is told. His comments tease by providing enigmatic hints, but never the full truth. He is a frequent commentator on Shadowland under the moniker "Laughing Man" with the signature "Ha! Fraggin' Ha!". He is a reluctant knight, not wanting to save the world, but often knowing he is the only one in a position who can do so. He has been described as the embodiment of chaos - unpredictable, mercurial, and usually quite detached.
He believes that in another 2,500 years, metahumanity will have developed both the magic and the technology to defend against the Horrors. He is an immortal elf who has frequently fought the Horrors, and has so far kept them from prematurely entering the Sixth World. Harlequin, aka Har'lea'quinn, Caimbuel, or Quentin 'Quinn' Harlech, is one of the most powerful individuals in the Sixth World.
