The Mercer House (known to mundanes as "The Grand Inn") is administered by an elderly, retired Redcap named Parsifal. He and his family live within the Mercer House, the better for Parsifal to attend to his duties. He oversees all clerical functions of the House, but many of those duties are shared by his assistant-turned-wife, Maredudd. Parsifal still proudly wears his red hat, though this may simply be a way to hide his ever-receding hairline. Their eldest, Andrea, is currently in training at Harco, and their other two children, Elspeth and Ingrid, are ages 9 and 5, respectively.
Also known as Guglielmo de Firenze, "Great William" is a great beast of a man, standing eight feet tall, and barrel-chested. To those who know him, however, his appearance is almost comical, given his shy, pacifist nature. He has long, unkempt, dirty blonde hair, and brown eyes. He is even-tempered and quick-witted, having extensive knowledge of Hermetic law and various arcane lore, and even has some knowledge of Hermetic theory. He was apprenticed under Horst of Fengheld, whom he idolises to this day. Great William currently serves as the official Tribunal scribe of Stonehenge. He has a pair of boots that can cast Seven League Stride unlimited times per day.
Also known as Sir Guillaume d'Arras, the nickname of "Little William" is something of a joke. He is a minor landless knight of northern France, standing at nearly seven feet, and is built like an ox. With shining golden hair to his shoulders, and sparkling blue eyes, Guillaume represents the epitome of Norman breeding. His real age is thought to be somewhere in his fifties, though he appears in his late twenties due to an early longevity ritual. His martial prowess is unmatched by any at Gallus Florensis, and he likes to boast that William Marshal remains the only man ever to have bested him in combat; he bears the scar on his lance-arm proudly.
Guillaume wears a fine suit of magical chainmail crafted for him by Justinius Tremeris. He carries a small arsenal with him, and bears an old-fashioned kite shield embossed with the image of a phoenix. He is accompanied by a magical destrier named Champion.
The youngest Redcap in Stonehenge, Edgar is just out of his teens and always feels the need to prove himself. He is extremely attractive, with black hair and green eyes, and spends most of his downtime trying to woo any and every pretty woman he finds. He is not particularly liked within the Order or even his own house, and has no magical items.
The hardest-working Redcap of the tribunal, Jasmine is rarely seen at the Mercer House, as she believes that message-bearing is the least important duty of House Mercere. She spends most of the year travelling about Stonehenge, Loch Leglean, and Hibernia, keeping abreast with politics both mundane and Hermetic. She is rumoured to be the best-informed maga in all of the Isles.
Jasmine possesses a magical skiff which can sail across both water and land, at great speeds; she also carries a ring which renders her (and conveniently, everything she touches) invisible.
Lady Isabelle d'Arras is Little William's younger, fae-blooded half-sister. Their shared father (a retired Redcap) is a minor noble in northern France, but unlike Guillaume, Isabelle's mother was a swan-maiden who captured the aging widower's fancy. Isabelle has inherited the ability to take the shape of a swan; due to her skill at flying and on the water, she is responsible for bearing messages across the English Channel. As a result, she is frequently seen at the English Mercer House, despite officially serving the Normandy Tribunal. She is a gorgeous woman with long golden curls and grey eyes, and her physical beauty is matched by her musical talent.
Isabelle has an enchanted feather which causes her clothing and items to change shape whenever she herself changes shape, allowing her to carry messages, vis, and equipment while in swan form.... Not to mention allowing her to resume human shape fully clothed! She also possesses a magical leather bracelet that resizes when she changes shape; when activated, the bracelet creates a favourable wind at her back, allowing her to fly nearly as fast as a falcon.
