The Keep on the Shadowfell
Popnlockit is a shifty doppelganger warlock. His true form is still unknown, as he is constantly changing his shape. As a doppelganger he enjoys assuming the form of others to persuade people, or just to cause confusion and mass annoyance. When it comes to battle Popnlockit usually drops the shenanigans to focus on the fight unless he deems the battle unworthy of his time.
