Obtain 10 samples of Plaguehound Blood.
My traveling companion, Fiona, runs a small vendor's shop out of her caravan. She and I, along with our friend Gidwin, are all on our way to Light's Hope Chapel. I'm sure you can join us, if you like... though Fiona might be a little mad at me.
Fiona always forgets why she's mad if you give her a gift. Kill some of the plaguehounds north of here, then bring their blood to Fiona at the caravan, down by the river. She'll love it. We'll talk again there.
