I was built by a human inventor:

>First few months as a Defibrillator

>by the end of my 1^st year I was built to be a proper Heal-Bot powered by my original Defib body

>After spending decades being my master’s first aider, he died of old age

> I spent a few decades reading my master’s notes so I could learn how to repair & upgrade my self

 

>Now I am adventuring, healing my new friend with the power of Gond (God of craft: Toothed cog with four spokes)

>Hobbies: wood carving & Junk sculpture making
