Free League
This ain't no faction and nobody tells them what to do. The ideas that any berk knows the truth and everybody else's wrong - well, that's a chance a body shouldn't take. Who's right - the Guvners? The Mercykillers? The Chaosmen? Since when does a smart gambler play all his jink on a single throw?
The short and long of it's simple: There's nobody who's got a sure key to the truth, so it pays to keep the options open. Maybe the multiverse is like the Lost say, but it could be the way the Godsmen tell it. Side with one view and find out it's wrong and, well, a fellow comes up a loser. There's no wisdom in that!
Still, a body's got to belong to something, if he wants to stay alive. The Free League's kind of an informal group of like-thinkers. They share news, pass around jobs, and watch each other's back. Hey, in a place like the planes, a body can't be too careful.
There ain't nobody tells an Indep what to do. They hire on with whom they please, insult whom they dare, and drink with the rest. Every creature's free to find his own path, his own meaning to the multiverse, and what works for one probably isn't the answer for another. Pure fact is' there's a lot of truths out there.
Some figure the Indeps to be cowards, afraid to play a stake on the truth, but Indeps see themselves as free thinkers, refusing to be shackled to some blind ideology. Truth is, there are some that don't want to make the choice, for fear of offending one power or another. Then again, there's plenty of folk seeking to make their own truth - maybe even start themselves a new faction.
Allies and Enemies
Because Indeps have kept themselves free of a single philosophy, most other factions view the Free League with a cynical neutrality. Indeps are just about anything in others' eyes: useful mercenaries, potential recruits, or dangerous spies. Rival factions'll use the Indeps in their various plans, but few would ever trust them. Only the Harmonium, with it's rigid beliefs, takes a strong stand against the Indeps.
Powers
Obviously, the free-thinking Indeps don't have many preferred powers. First of all, gods of liberty and freedom aren't exactly commonplace. And besides, even a deity'd blanch at trying to wring a consensus out of members of the Free League.
Still, most Indeps agree that two powers in particular are fairly decent bloods: Trithereon and Shinare. They're both Single-sphere gods (Trithereon of Oerth, and Shinare of Krynn), but as powers of freedom and liberty, the faction finds them quite upright.
