“One thing I’ve noticed in this line of work is how many of the
Ancients’ left-behinds also have some means to deter
intruders. Why would they lock these places up so tight before
disappearing without a trace? Was their society simply so paranoid or
dangerous they felt the need for such defenses on everything they
built? Or did they plan on coming back someday, and sealed up their grand wonders as you might lock your door before going on a trip?"
