Know of any eerie tales?

Quest Text Does that soldier have his mouth sewn shut?
He never has anything to say.

Summary Eerie tales? I've heard talks of graves and treasure at the Biraghi Den...
But such a fortune doesn't befall just anyone.
You need to have earned it through good deeds.
Have you done much for Serendia?
If not, you may as well forget about such good luck.
Or find yourself in the clutches of Biraghi NPC Knowledge bandits...
