Gears of Faith

Keren is a sworn knight of Iomedae, proper and disciplined in every way. Her girlfriend, Zae, is the opposite a curious gnome cleric of the clockwork god, who loves nothing more than the chaos of her makeshift hospitals. When a powerful evil artifact is stolen from a crusader stronghold, both knight and gnome are secretly sent to the great city of Absalom to track down the stolen bloodstone.

Sure, they may not be the most powerful or experienced members of their organizations, but that's the whole point -- with legendary champions and undead graveknights battling at every turn in their race to recover the stone, who'll notice one young knight and her gnome? All they have to do is stay alive long enough to outsmart a thief capable of evading both gods and heroes.
