Hm... two thoughts bouncing around right now, wanted to get your opinions on them.
Heritors of the Unknown (Better name pending), a group of Duskblade/Totemists that have taken to offering the souls of the world to the Far Realms in exchange for power, while channeling the power of the far realms into this world, applying it's twisted physics to this world's own, and the
Rune Sages (Better name also pernding), a group of Binder/Sorcerers who go back to the very roots of magic, eventually learning to wield the awesomely powerful spellcasting style of the ancients.
Rune Sages for the win. Binders have so much incredible flavor and potential.
