it even seemed to explain all the routes in echo and echo tsr - the evil being transcends time and space able to manipulate multiple time lines, heck two of the routes in echo actually have dialog that implies the evil being is aware of choices made in a alternate time line (when a certain choice to kill a certain being results in the dialog "comes full circle") Even a time travel event that links echo tsr and echo together (too much spoilers to mention directly but it permeates in multiple timelines of both games)
