Klimmek is a trader who makes deliveries from Ivarstead to High Hrothgar. He can be found on the road out of Ivarstead to High Hrothgar. Klimmek and Fastred were romantically involved until she became more interested in Bassianus Axius.
Klimmek usually delivers supplies to the Greybeards at High Hrothgar, but this time he is unable to do the trip. The Dragonborn may receive the supplies and do the trip for Klimmek.
Klimmek can be persuaded to express his feelings towards Fastred and make her change her mind on leaving Ivarstead with Bassianus Axius.
