Mythical Creatures [EDITING]

Shade

A Shade was a magic user and Sorcerer possessed by a spirit or spirits, thus becoming a new creature. While Shades could originally be Human, Dwarf, Elf, or Urgal,  once possessed they adopted similar traits, such as extreme strength and magic proficiency.

Shades were usually created when a sorcerer or sorceress summoned a spirit or spirits that he or she couldn't control and consequently became possessed by it or them in both mind and body. Some magic users willingly submitted to the control of spirits in order to gain greater magical power, thus becoming a Shade. To become a Shade, a humanoid form is not required. Many Shades have been formed, but most Shades self-destruct shortly after creation. Shades which survive the volatile natures of their formation were rare indeed.

Regardless of their original appearance, Shades become very thin and pale after their transformation. Their eyes and hair became dark red: Their eyes are maroon, "as red as wine" and their hair was crimson, "as red as blood." Shades resembled humans in other ways, with lean bodies "like a runner's, thin and compact." Shades could age, but this process was different to the aging seen in other species. 

Since only an evil spirit would welcome the opportunity to enter and control the body of a living creature, Shades were altogether vile and cruel. Nevertheless, they were also intelligent and cunning, as well as skilled in magic and swordplay. 

Once created, Shades were extremely powerful and dangerous, among the most feared creatures in the world. In addition to sorcery, Shades were gifted with superhuman physical abilities, many times greater than the fittest humans. These abilities included supernatural strength, speed, stamina, pain tolerance, as well as unmatched senses: A Shade could see as clearly at night as they could during the day, track scents at great distances.

Perhaps their greatest ability was their resistance to death. A Shade could only be killed by being stabbed through the heart: otherwise, it would merely be temporarily disembodied and would reappear elsewhere in spirit form before returning to a body, healed. This process was unpleasant for the Shade and extremely painful, but had no lasting consequences.
