Wario

Wario is a science guy with a complicated history with Journey and Desmond. He was Mariette's apprentice in Alabastra when Smashmouth got stuck in the past. He was a wee lad who let them into his tower. When Mariette gave birth to Journey and Destination, she escaped with them. Wario, being the eldest of the children, took car of the girls while they grew up on the run. Journey spent her life being chased by her father's people and hadn't seen any of her family in at least 100 years (until we ran into Wario). Journey recalled the Dream Dircc entered that one time; they were being chased through a guildhall in Vasselheim. Wario was able to lead them to a secret passage behind a tapestry but Destiny couldn't fit and stayed behind to provide a distraction. Journey fled with Wario but they decided to split up to lessen chances of being tracked, and 50 years later we ran into Wario doing necromancy. What happened in those 50 years?? 
He's a gnome science man who was conducting DNA research in Jorenn. He's not evil, but not not evil, ultimately is going to trial for killing Nergal, but TACOSE takes him for some reason. What happened was his employer (he could not say who) hired him to reanimate corpses since they were easier to control than the living. He left hints for Smashmouth to figure it out because he hated doing it and wanted an out. He's lost count of how many people he's killed and assumes there are others like him. Recently, he escaped TACOSE custody and is on the run. "Science is real and it's coming".
Lab Notes:"We need RESULTS. Speed up the timeline. Westruun was a disaster. Nevermind your funding, your life will be forfeit." - To Wario "Water supply successfully altered, burns suspects nothing, the hearts are the key" - From WarioHe's missing (I'll look through notes later to see if we know where) and the Cerberus Assembly in Rexxentrum has tried to kill Wario before.
