Turn of the Century team of Occult Heroes, Excalibur.
The Excalibur Group is a private organization funded by a trust left by Lord Excalibur's widow, (mother of noted Para-natural Rights activist, Prof. Charles Excalibur.) Lady Excalibur was a student of Spiritualism, and she left a third of her fortune to a mysterious man named "Marten Broadoak", who seems to have some dealings with matters of the Occult. The Group has been known to have connections to Stephen Sanderson (The Infamous "Doctor" of Strange Lane) and Sir Reid Richard (of the King's Phantasmal Four).
1. Merlin Ambrosius was a powerful and immortal wizard who served the mystical 'Arthur' of legend. He is also the guardian of the 'Tower of The Firmament', one of the structures that support and keep separate the many worlds of Creation. Should the Tower fall into the wrong hands or be destroyed, none can guess at the huge consequences that would befall our world and others. To this end he arranged for the foundation of the Excalibur Group. Each member was carefully selected for their unique skills and strength of spirit. As 'Marten Broadoak', Merlin makes rare appearances and orchestrates his labyrinthine schemes, but spends the vast majority of his time in the Tower itself.
2. Mordred is the sovereign Lord of Orbis Alia, also known as 'Annwn', the homeland of the Fair Folk. Orbis Alia is a world that cleaves to our own, and in fact they are but a step apart to those who know the ways of it. Because of this, the fate of both worlds are always intertwined. Lord Mordred is as clever as he is ruthless, and hides his true intentions beneath layers of subterfuge and misdirection. He has recognized Merlin's Excalibur Group as official ambassadors to Orbis Alia for the present, and has even sent a representative of his own to join their team. His reasons for this are mysterious, and his beneficence highly suspect.
3. Peter Wise was an Agent of the Crown, part of Queen Victoria's secret 'Dark Bureau'. He dealt with supernatural goings-on for years, often getting his hands dirty in the service of his country. An encounter with a Class XIII artifact (cursed, hexed, or inauspicious items), the Ebony Sword, finally pushed him over the edge. He left his job with the government and joined the Excalibur Group. Now he fights for his country as the Ebony Knight, cursed to an immortal life of bloodshed until he can wash the stain from his soul.
4. Eliza Broadoak was once Kuwa Tsurayaba, a shinobi warrior from Okinawa, Japan. She was a member of the Migite (右手: Right Hand) ninja clan, so called because they functioned as the Shogun's right hand. After the shogun was deposed, the Migite Clan went into hiding, while another ninja clan, the Hidarite (左手: Left Hand) clan, that had also served the Shogunate, pledged their loyalty to the new Meiji government. A surprise attack all but wiped out the Migite. Kuwa was the daughter of the clan leader, and the next in line to receive the secret arts of the clan, a set of techniques known collectively as the 'Soul Knife". She was rescued at the last moment by Stephen Sanderson, an old friend of her father's. She was re-situated in London, under the care of the wizard, Merlin, who adopted her under his alias 'Broadoak'.
5. Byron Broadoak, a blood-descendant of the pre-Roman warlord, the legendary 'King Arthur', adopted son of 'Marten Broadoak'. After his parents perished in a terrible accident, Merlin approached him and offered him two choices. He could take the Ebony Sword of Might and have eternal life-- or the Golden Amulet of Right and have the power to protect others. Choosing the Amulet proved his worthiness to be the Champion of Britain and a representative of our world to the other worlds of Creation. The Amulet gives Byron great powers, but it is his noble spirit that guides his actions and by his example, the actions of the others in the Group.
6.Meghan Faire, a child kidnapped by Fairies from her home in Cottingley, England and raised among them in Orbis Alia as 'Glorianna'. She is Lord Mordred's gift to the group, a gifted practitioner of Fae magic, and a guide to the world of Orbis Alia. She is also his spy, and is under the threat of great retribution if she doesn't follow her Lord's commands. Meghan has long obsessed over our world, known to the Fairies as 'The Firmament'. She voraciously read the colorful penny dreadfuls her people would bring back from scavenging trips to our world, and her understanding of human society is built entirely on this basis, much to the consternation and confusion of her new teammates.
7. Conrad Wegener is from one of the other worlds that connects to our own, a dimension metaphysically Below ours. His father is a mighty demon warlord in his homeland, but Conrad has lived most of his life in our world with his mother's family, protected by magical disguises. A romantic soul with a heart for adventure, Conrad is always up to something. As a hybrid of human and demon, he's learned to step between worlds with an ease unheard of throughout the worlds of Creation. He is also a superb fencer, and a first-rate prankster.
