Xill

The xill were horrific insectoid creatures originated from Ethereal Plane.

Description
Xills had four-arms and two strong legs, they looked like a cross between a lizard and insect.

Combat
Xill could magically shift themselves between the Etherial and Material planes. They used that ability to hunt. They would surprise their prey by jumping out of the Ethereal Plane and raking them their claws. Without killing their prey, xill injected them with a paralytic poison in their claws. Next, they waited for the prey to become completely powerless from the poison. Once the victim is defenseless xill took them back to the Ethereal plane for unknown and terrifying purposes.

Ecology
These creatures hailed from one of the dark and sinister demiplanes in the Ethereal Plane.

History
True origins of xill remained unknown, although scholars linked their existence to the mysterious wizard Keraptis. He created the demiplane and the insectoids to be able to use them as collectors of powerful artifacts, seamlessly slipping into the Material plane to collect the item or a person and disappearing without a trace.
