Wraith-er demons were a humanoid demon species capable of assuming human form and "infect" humans, turning them into second-hand Wraith-ers.
Physiology and Powers
Wraith-ers had the power to make themselves look human but only for a short time, ranging from ten days to two weeks. Afterward, they slowly reverted to their demonic visage and become more violent. Humans that remained close to the Wraith-ers were infected and slowly transform into Wraith-ers themselves, though the infection could be reversed with Cylenthiam Powder.
Wraith-ers had scaly skin, spines on the back, seven fingers, pointy ears, sharp teeth, and solid yellowish eyes. Their green saliva contained a substance called Penloxia.
