Demesne Core

As I remember it, I was a corporate drone from Earth that has been reincarnated as a Demesne Core in the fantasy world of magic and mana. Armed only with my Earth knowledge and a bare bones system, I'm going to have to work hard to protect myself from the natives. Fortunately, I've been given a powerful Demesne Companion to help guide me and act as a powerful defender--wait, what do you mean my Companion is missing?  What to expect: I am a native English speaker but not a good writer. This is my first fiction. Don't expect much. Written in first person stream-of-consciousness style. Footnotes--yes, footnotes.
