You have helped Mögr in Zelem-melek, and he has received word that the Orc-watch in the Redhorn Lodes is in need of aid as well.
'Had enough of Zelem-melek, have you? Well, you will always be welcome in the Twenty-first Hall, ${PLAYER}, for the services you did us.
'There is a goat waiting in the stable that already knows the way there, if you do not wish to take your chances on the road. It is a difficult journey to the Orc-watch....'
Avar is in the Orc-watch in the Redhorn Lodes, a long ways from the Twenty-first Hall through the many winding passages of Zelem-melek.
Mögr has invited you to ride a goat to the Redhorn Lodes if the journey is too difficult on foot.
