D'arque Justice is a group of magic-based heroes who fight supernatural elements and handling situations deemed unfit for the traditional super hero groups. Some of the team members are spellcasters.

It also has a secondary role of training those with supernatural abilities in controlling their powers and help foster a friendly human-supernatural relationship. This is done through its Collegium of the Arcane, a place where aspiring sorcerers of talent and noble inclination can learn the basics of the mystic arts. Due to the history of its members and founder, the Collegium has become a group closely associated with the superhero community. The school consists of Dimitrios, the former Earthlord; his six permanent students including the current Earthlord; and a variable number of superheroes and talented normals who attend on an irregular basis to learn finer points of magic. The Collegium also acts as a centre of magic research; heroes puzzled by wizardly references or ancient runes or myths bring their questions to The Master and tend to gift him with magic talismans and crumbling scrolls they accumulate in the course of adventuring. The existence of the Collegium is generally known only to the superhero community and its sorcerous enemies; the fact of its existence has not yet been discovered by the press.

1908 saw Dimitrios Nikolos chosen as the next Earth Lord, the Master of the Mystic Arts on Earth. In 1915 Dimitrios joined the Freedom Squadron and took part in world war one. In 1923 Dimitrios regrouped the Squadron to fend off an invasion by Tyrannus at Ayers Rock, Australia. In 1935 Dimitrios defeated a Tsaurid scout force with the help of some Lemurians. 1944 saw Dimitrios battle Tong cultists in China only to be defeated by the Master and imprisoned on Elseworld. He would remain trapped in this other dimension until 2005 when he was rescued by members of the Parliament of Nature. Because he was in a state of mystical suspended animation Dimitrios was still only 56 instead of 117.

The Parliament having recently lost its current Master of the Mystic Arts to a supernatural monster conjured by the Cult of Kali offered Dimitrios the position once again. He agreed and leading his mystic rescuers, attacked the Cult base killing them all and destroying their summoned demon. After this Dimitrios took on more of a teaching role, at first training new spellcasters and later those with supernatural abilities. In the years since, Dimitrios has tutored many heroes in the mystic arts and is considered to be among the most knowledgeable (if not necessarily most powerful) mortal sorcerers on Earth. Dimitrios does not tolerate frivolous use of magic powers in his presence.

Dimitrios does not go on minor missions. He generally does not answer questions straight; like any other frustrating oracle, important questions posed to him about this magical villain or that ancient spell will often be responded to with riddles or warnings instead of facts.

The D'arque Justice team operates out of Collegium but they are not a superhero team. Its members may be inclined to join other superteams, and may be encountered in the normal crossover way: fighting crime or otherwise trotting around on their own turf. But within those constraints they’re still an effective tool for a campaign. One of those frustrating half-answers from Dimitrios can be enough to keep an adventure on track. He’s not always (or necessarily often) available, but the assistance of one of his primary students can enliven an episode. If you keep in mind that they simply cannot be used as some sort of data bank for the player-characters, they will prove to be an NPC asset to a campaign.

The location of the Collegium appears to be a focal point for mystical energies with a nerve center of dragon ley lines running beneath foundations, the veins of magic running through the Earth. Years before any permanent Western European settlements, a powerful Native American Indian Shaman cursed the land to bind a chaos-entity to that place and bar her full access to Earth. The site continued to serve as a place for arcane Native American Indian rituals. Shamans were known to journey here for vision quests. With the arrival European colonizers, the site became used for pagan sacrifices. Before any permanent structures were built on the land, it was used as a Potter's field: a mass grave for paupers and inmates from the city's first penitentiary. It is unclear who first built on the site, but it housed a Satanic cult that performed human sacrifices. The original structure was destroyed in a fiery blaze, as were the subsequent five buildings on the same plot of land. Over the years, the various buildings were used as a flophouse for beatniks, a notoriously bacchanalian speakeasy, a failed nunnery, and the lair of a Puritan witchfinder who tortured immigrants in the basement. The current structure is actually the seventh building constructed on this site. Its architect and details of its structure remain shrouded in mystery, and the building itself continues to grow and change. Before being purchased by Anoushaka Delama, the dwelling gained the local reputation of being haunted. It was the structure's supernatural aura that originally drew Anoushaka and the Parliament of Nature to it. Before claiming the mansion as Delama rid the building of the chaos entity and imprisoned her familiar. The Collegium is warded by powerful spells cast by Anoushaka and others on drawing on the inherent mystical energies of the site. It also houses the Nexus of All Realities, the centre of all other dimensions.

The Collegium building is a three-story Victorian-style brownstone townhouse built in the French Baroque architecture design with a Mansard roof. Due to its mystical nature, the exact dimensions of the building are variable allowing the building to seem more spacious on the interior. Additionally, furniture, doorways, corridors, and even entire rooms will move creating a labyrinthine distortion of time and space. The first floor houses the foyer, drawing room, library, living room, dining room, and kitchen. The second floor consists of a study, private bedchambers, and multiple guest quarters. The third floor is composed of the meditation chamber, mystical library, and the storage area for occult artifacts. Finally, in the basement are storage rooms, the laundry room, and a magical furnace. There is a utility shaft for servicing the furnace that leads from the basement to the third floor meditation chamber. An alleyway leads to a small courtyard and stables where Sif's steed Aethon is kept. There is also a bathhouse with waters that few mortal beings can survive, a medical recovery chamber inhabited by ghosts, staircases, and several doors acting as gateways to other dimensions.
