Guard Heiac:
He is Guard Stan, who guards the southern entrance to Oren Castle .
Between you and me, though, I'm not sure how reliable his story is.
He may be a guard, but he's always been pretty easily spooked, and he has a very active imagination. It's possible he saw nothing more sinister than a fox!
But by all means go and speak with him.
I'll hang onto this letter of recommendation, if you don't mind.
