Carbon

Carbon isn't sentient. It is a semi biological robot used by observer to experience the universe without destroying it. Observer controls the bio bot and is the one speaking & moving. When in control of Carbon Observer uses that as their name. 

Carbon can most often be found exploring & studying worlds and their flora & Fauna. They delight in discovering things new to them and finding 'stories'. While Carbon enjoys written stories the stories they find the most enjoyment from are the ones being lived by people currently. Carbon will follow around a particularly interesting individual to watch their story unfold. They can interfere but often take a less involved approach to preserve the fun in seeing what choices that individual will make without their assistance. Carbon will also pry into people's 'backstories' wanting to know everything there is to know about someone.
