Priest Cain:
Dwarves have been able to inscribe weapons and armor with incantations, friend--their skills with metals are unrivalled throughout Aden.
But what if Jacob were inscribe his necklace with something other than an incantation? What if he left a message within his necklace as he lay dying? A message that would pinpoint his killer?
It seems that somehow that creature was able to hide itself in the message, and when the necklace touched the burning incense... we must have released it.
"I see... I think."
