Wow, someone with something akin to "grudge" getting the best support they can ever get: a rezzer.
@Saxfire
They're guarding the burial of heroes, something with strong national or religious significance, like the Tomb guards for the Tomb of the Unknown Soldier. From their words, there's probably more ceremonial guards on duty and there was something that threw everything to the shitter, or they decided that night duty would be taken by two people only. Well, who knows how far back in time did the cemetery get founded, and how many generations of heroes are in there. Due to the heavy religious and national implications if ever the cemetery is desecrated, I wouldn't wager people out of the really desperate trying to tomb raid the area, so the guards aren't that many, but they should still be there.
Also, all it takes is
one person rediscovering that place. Remember, Licht found it due to a rumor in the adventurer's guild; who's to say some other adventurer would peep into it? And like any good player of Evil Genius knows, once one enemy agent (in this case adventurers) comes in, expect there to be ALWAYS enemy agents popping in.
Edit: Whenever she gets revived like that with that face, I can't help but think she says she's revived like that like how patapons says they "reborn" when resurrected XD
