FLASHBACK
"Hey, Wolfram, you still haven't told me about the fourth type of parasites."
Arthur was facing his brother, the two filling their stomach with some freshly cooked meat. Leiu, as usual, was endlessly swinging his huge sword on the size, not minding the eerie atmosphere or the suffocatingly hot weather.
As he heard Arthur, the Joker seemed to have remembered that topic. He pretended not to notice his brother's intense gaze and slowly enjoyed the rest of the food before licking his fingers then finally answering:
"In terms of Hierarchy, Calypso parasites are considered the highest. There's only three in existence and they are born infertile, one was killed but I doubt the other two will die anytime soon. In fact, Zaarae only created two types and the rest were born of mutations or copulation between a parasite and a different race. The records mention the Calypso parasites and the Night Parasites."
Just kidding, it's triple release but it'll be a bit later.
