Climb down the ladder and in the closest room you will find the child's blanketsitting on a table. Take this blanket back to Brother Omad. He will then ask you to find Brother Cedric.
A missing Brother
Head north-east of the monastery by following the path. Once you reach the fork in the road you will find Brother Cedric. Speak to him and you will find out that he is drunk. He will ask you for a jug of water so that he can become sober. Give him some and then he will ask you to help fix his cart. To do so you will need some logs; hand them over and then he will ask that you tell Brother Omad that he is on his way.
