Xera is about an invasive species of alien known as Xerankari. They live only to feed, what’s their food source you might ask? Well I’ll tell you, it’s humans. They live in Underground nests to escape the blazing heat of stars. They treat humans like Humans would treat cattle locking them in cages saving them for later. They will hunt humans into extinction unless someone or something stops them.  They only attack when they feel their enemy is weak, and after Earth’s 3rd world war, that’s exactly what earth is. These monsters have black scales for skin, blue Blood, a mysterious black mist that gives them power, evil glowing red eyes, razor sharp teeth, immortality and an endless hunger  **************************************************************************************************************************************************************************
