Andrac

Also known as Star-Eaters is a black, shadowy figure roughly in the shape of a human. The size depends on the number of traces used to make it. Its eyes and throat shine brightly like a star, which is probably where the name came from. They possess long claws that, when hit by, turn the skin black. Andrac are faster and stronger than humans and can learn. They also have the ability to track the nether back to the user. They can only be hurt by ether or ether imbued weapons. However, once they've been hurt by the ether, a nethermancer can syphon the nether from the Andrac as long as the injury hasn't healed. Star-Eaters is the original name and later they are dubbed Andrac, an old Mallon word, most likely in an attempt to pin their creation on Mallon.

Creation (Dante and Blays style)
To start, go to a location that's seen a lot of death. Battle fields are ideal. Expose the netherworld to ether. The best way to do this is to shadowalk with a torchstone. Once back in the world of the living, illuminate the same area you did in the netherworld with ether. Small, black star shapes should appear. These are traces. A trace is nether that's made contact with a soul. Raw nether and traces cannot be mixed. Only traces with traces. To do this, create a thin trail of blood from one trace to another and they will combine to make a bigger star shape. Keep doing this until you have the desired size.

If your Andrac's been blasted back into the netherworld, but not torn apart, you can create a doorway for it to come back. The doorway requires nether infused bones to be placed in a hexagon pattern on the ground with 3 bent flanges and big enough for the Andrac to pull itself through.
