A Champion League, an elite group of renown heroes. They go out and fight injustice throughout Tamriel. Oh, and they have a tower called the Overlook Tower and it's floating in Oblivion. Their members are a princess, a shapeshifter, a guy with a super enchanted ring, a stealthy guy in a cowl, an archer, a fast guy, an underwater king, and a super guy...
... but seriously I want a Justice League -ish type faction. Reserved for all of us Paragons of virtue, duty, honor, and justice.
