Icewind Dale 2

Just a generation after the events depicted in the
first "Icewind Dale", a new threat has appeared in the Northern region
of Forgotten Realms. Something - or somebody - is trying to cut off the
Ten Towns area from the rest of the world. Hordes of monsters invade
peaceful towns and kill their citizens. You play as a party of
adventurers who happen to be in the region, and upon their arrival they
are requested to help to defend the town of Targos against monster
invasion. But once they have accepted the quest, the adventurers
realize it will only be the beginning of a long and perilous journey...
