I got the ghoul bestiary and I need it for one of the first quest. However I can't did into the remains. Any ideas?

Act 1 ? Can`t get in the crypt ? First make sure that you have the bestiary entry for Ghoul in your journal under monsters. If you do then proceed with the main quest until you get to the part where you have to earn the villagers trust . There should be 3 people that you need to do something for . Odo , Mikul , and Haren Brogg . Mikul is the one that will let you in the crypt .
