Guard Praga:
Ah ... that book. But that book was quite interesting. And I bought it for money. I can't give it to you for free.
Well, how about this? Recently, I was making rounds in the Ruins of Agony when I happened into a fight with the ruin zombies. At that time, I lost a pendant that my mother left me before she died. Please find it for me. Here, this is the chain of the necklace. See if the pendant fits it, and then return them to me, please.
Don't wrinkle your nose like that. A true believer like you will be protected by your strong faith. If you need direction, you can reach the Grim Ruins by journeying west of the village.
