Avatarbots are created by an organization named 'M3ND3L' that specializes in genetic therapy and genetics in general. Using a 'volunteers' DNA and by 'borrowing' a few brainwave samples using advanced technology, lab specialists take the data and use that to create a 'persona' based on what they found. Species/height/whatever doesn't matter and can even be customized by the volunteer. (Unfortunately they need to pay like twice as much for that to happen.) This means Aven had to pay around 1300 dollars just so he could make AIDEN. Avatarbots are reliable, and even come with their own specialized magic! This is the only 'free' option that volunteers could change, and more 'complicated options' need to be paid for. Kind of like a shitty f2p mobile game. These bots rarely break and can be about as tall as a child. For those that want to have a 'resupply' they either buy a kit from M3ND3L (thus wasting more dollars) or get a robotics company to go to M3ND3L and get the parts themselves to help with resupplying. You know how hard it is to fix something with your genetic footprint on it?
