Ursh and Drek were hired by Gundren Rockseeker and his two brothers to guide a caravan to the mountains of Karameikos. Gundren had a map. Ursh and Drek were to meet the brothers at the village of Orlane, from which they would then follow the map to the mountains to the north west.
But the brothers were gone when Ursh and Drek arrived. Initially the villagers all claimed to have never seen the brothers, and Ursh and Drek searched along the road from Kelvin. Eventually a villager leaving the village claimed the dwarves had been in the village, but had then disappeared in the night.
Ursh and Drek reported the missing dwarves to a city guard captain in Threshold.
