It's revealed in the Prerelease that Magus ordered Heckran to protect the spot over which Lavos sleeps.That's very interesting, I wonder why they chose to remove this detail in the final release? There's one thing that I don't quite understand though. Why would Magus order Heckran to "protect the spot over which Lavos sleeps"? Was this some kind of back-up plan in case he either lost or failed to summon Lavos the first time (in the original Middle Ages timeline before Crono and party interfered)? Surely he didn't believe that some random person would just dig deep in that exact spot and accidentally awaken Lavos. And could Heckran really be over 400 years old? Mystics might have a longer lifespan than humans, but this just seems too much. I'm assuming that Magus can feel the dark energy of Lavos or something which is how he knew the exact spot where Lavos was in. Does this mean that Heckran's Cave in the Present time is where Magus' Castle was in the Middle Ages? Or could Magus summon Lavos without actually being directly underneath it? And lastly, would Heckran really choose to continue guarding the same spot for over 400 years after Magus was defeated and disappeared? If so, that's quite some level of dedication! Maybe Heckran was still hoping that Magus would return some day.
All this just doesn't quite make sense. Perhaps that's why this detail was removed before release? Or does anyone here have any ideas how all this could have been explained in the game?
