whatever that is

Humans have a core made of their memories from the macroverse and their general psychology/emotions/etc. being transported into their circus avatars. It's made of their neuro scans and an additional heart. The heart is what keeps the avatar running in it's active state, and what keeps them from abstracting.

AIs have similar structures like humans. Except they lack a heart. While they can still feel emotions that can even feel as real as humans, much of it is still artificial. An AI doesn't abstract since they're part of the computer basically. But they can still be deleted or reset otherwise.

(Most have one single core but caine has two existing. Just that one has more control in the code.)

More stuff about cores.

Assets are just geometry. They can be easily created and deleted.
