In the world of the Dark Crystal, there are 2 races that share a soul: The Skeksis and the urRu. They were once a race known as the urSkeks, but were torn apart in an attempt to cleanse their souls. They split between good and evil, light and dark, tainted and pure.
Here is my concept of one of the first of their kind to die. The horrible empty feeling of being less than he once was, the Skeksis attemts in rage to murder his urRu counterpart, committing suicide as he does.
The urRu, feeling more loss and sadness works a ritual in search of comfort, knowing deep in his soul that it will soon end.
