My other favorite companion, Vexes has seen many different personas. He's been a renegade AI, a tiefling rogue from D'n'd, a human boy, and a cyborg. He is by far one of my oldest characters.
He was also a city.
This incarnation is an ISO (Isomorphic Algorithm, for those of you familiar with TRON Legacy), and tragically (and totally cliched, I might add... *sigh*), one of the last of his kind. Vexes and another ISO, Lianette, had just escaped the remains of Vespira City with the help of a User named Alec (More on him later). Alec leaves the ISOs to their own devices while he goes to tend to other things around The Grid. The two ISOs make there way to Altrax City. There, Vexes and Lianette change their appearances, and Vexes uses his musical skills to DJ at a club, where he eventually becomes known as the Zietgeist. Lianette started working in a garage. One day, while Vexes was working, a renegade AI named Malec partially derezzed Lianette and left her for dead,only for Vexes to find her and watch her die. Eric arrived a few cycles later, and helped Vexes when Malec came to derezz him. Since that day, Vexes has been travelling with Eric wherever he went.
Vexes feels he could've done something to keep Lianette alive, and carries a guilty consience as such. He also carries Lianette's disc, and a great knowledge of Thunder magic.
