Summary
A party of adventurers in Icewind Dale have discovered an ancient trail map that marks the location of a dwarven hold called Frostsilver. They are urged on to explore the site by a pair of dwarf brothers, who recognize it as their ancestral clanhold. Upon entering the place though, they find it occupied by goblinoids led by a pair of Underdark slavers.
