Anulin

Anulin are the leaders of the Renegades, and they hosts safe havens for anyone that wants to escape the "tyranny" of the great factions. They are highly intelligent and anarchists, so they don´t believe in any sort of government. In fact, they don´t have any leaders, and every settlement is independent of the other, they only ask for help when desperately needed, and won´t risk the secret and safety of their own unless morale demands it.

These anarchists also happen to be enormous flesh titans, that could easily crush any enemy, but they are weak around magic, which many factions have aplenty, so they prefer to be peacefully in their hideouts.

Speaking of their hideouts, they are very secretive about them, and very selective about who can join them and who will stay a lonely outlaw. Of course, everyone can claim to be a renegade, but to get the capital R, and the benefits of being in an open-minded faction that doesn´t impose any kind of restriction beyond secrecy.

It's their vow to be selfless, but they are not stupid, and anyone willing to join them must pass strict mental examination, and periodic inspections of whereabouts and acquaintances. Still, they´ve managed to keep a working faction for a long time and it hasn´t failed so far, so their methods must be good.
