Gnoll Escape

Objectives
Obtain Trapper's Keys from Dark Iron Trappers and use them to free 6 Gnolls from the Gnoll Cages.
 * Gnolls Freed (6)

Description
I know we were just attacking the gnolls ourselves, but I'm not about to let the Dark Iron capture them as slaves. For one, we found the thieves and took back what was missing, so justice is served; for another, whatever work the Dark Iron will be putting them to isn't something I want to allow.

Either way, the gnolls need to be freed. The trappers should have keys on them, so use those to open the cages.

Rewards
You will receive:

Progress
Be sure you free enough. I want to make sure a wrench gets thrown in the Dark Iron's plan.

Completion
That should do it! The more gnolls those fools have to chase after, the easier it'll be to keep them in line.
