Millenium Apocalypse Dragon Smaug: He’s… uh, well, a space dragon. He spends most of his time hibernating on a comet, but every thousand years that comet passes through Arda’s orbit - and Smaug wakes to feed. Obviously nobody’s around anymore who remembers the last time the Millenium Apocalypse Dragon landed, so we don’t know a lot about him. The way you hear it told, he’s just a mindless beast, but there may be more to it…
Khazad Rangers: In time out of mind, the ancient dwarven Kingdom of Erebor developed technology to heights even the modern world cannot surpass. But, it was destroyed the last time the Millenium Apocalypse Dragon Smaug passed through Arda’s orbit. The dwarves could have fought the beast off - if their jealous allies, the elves of Greenwood, hadn’t abandoned them on the field of combat. But they did. The Prince of Erebor and the Knights Under the Mountain fought bravely, but were annihilated, and the dwarven kingdom faded from all memory - until, almost a thousand years later, the Prince and Knights Under the Mountain were reborn as average high school students. Well, mostly average. The reborn Prince, Thorin Thrainson, happens to be the heir of a powerful but ruined zaibatsu that is heavily involved with the local yakuza. By day, Thorin Thrainson and his friends and cousins dominate the kendo team of Midgard Municipal High School, and have a bitter rivalry with the kyuudo team. By night they are the Khazad Rangers, masked and armored vigilantes and upholders of justice. They support industry and the common worker.
Sindar Scouts: These are the very same jealous elves of Greenwood, reborn as the prim and saucy kyuudo team at Midgard Municipal High School. Beautiful, debonair, and high-class, they have their own groupies, stalker paparazzi, and fanclub - and the fanclub is very zealous about seeing that their rules concerning the way the kyuudo team is treating are followed. By everyone in school, in the fanclub or not. Obviously this doesn’t go over well with the kendo team, and (re)sparks a bitter rivalry between the two factions. Their antagonism has a secret identity, too - the Sindar Scouts, another group of honorable vigilantes, but with very different political affiliations than the Khazad Rangers. The Sindar Scouts favor ecology and the arts, and are unapologetically classist about it. If you can’t afford grace or elegance, get out!
Took Adventurers: A family tradition of masked mischief and merriment, passed down through the ages. They need no purpose other than the fun of stirring things up, but often get involved in the great Events of their time anyway. While they always fight for good (and good humor), they’re professional wildcards and love breaking rules. They’re unfailingly polite about it, though - dashing bandits who always leave a calling card.
