Go to 'The Herb Shop' (S2E2NEN from the Cathedral)
ASK ROOT MURDER, the root 'shows' you the murder of a young girl.
ASK HAG MURDER, she tells you to find the odd shaped tree in a valley.
Now go to 'In A Dense Thick' (from the Herb Shop it is S,W,2S,E,OPEN EAST,3E,2S,2E,2N,U,2S,3E)
GET SKELETON COPSE, GET DAGGER SKELETON
Now go to 'Barracks' (you can HUNT CONQUISTADOR to get there)

He summons Castan de Merida, who will kill himself.
