Constance

Constance is the Elkian also known as Funeral Lily; she is the system AI that announces when "players" wake up from their comas... but also becomes the default system to announce when they die.  

Of all the Elkians programmed into the Acadia System, Constance was given the least personality; she is very blank, straight, and by-the-book.  She doesn't play along well with Kayne's affections, but allows him to generally do as he pleases.
