Grimm-Apathy

The Apathy is humanoid in shape, somewhat similar to the Imp, but are very tall, with long arms that reach down as far as the ground and extremely long fingers. They have hideous faces, resembling skulls, some even lacking nostrils, and low-hanging jaws. There are at least four variants to the Apathy's appearance, two being extremely hunched back, whereas the others stand taller.
The Apathy has the ability to use a scream that weakens their prey by draining their will. This works through remote proximity, but if the Apathy can see their target, the effects become much stronger. If the prey is startled, they are jolted out of these remote effects, albeit temporarily. Repeated attacks will weaken a target to the point of falling asleep while in combat, or even cause their death while unconscious. They also seem to have the ability to drain willpower from remote proximity, but it is still unknown how the Apathy kill their victims.
They tend to attack in packs, using their superior numbers and will-draining powers to bring down their prey and compensate for their lack of inherent physical strength. A single Apathy is less powerful and will take longer to drain willpower than it does for an entire pack of them. When alone, an Apathy is not aggressive and seems almost timid. Despite their slow movement, emaciated form and general lack of physical power, the Apathy are surprisingly resilient to damage.
