From publisher blurb: The dreaded Ice Forest! Once a safe passage to the north, now the forest's evil magic seeks to trap and confuse travelers with ever-shifting paths full of terrible dangers. New monsters, new magic items, new magics! This adventure for character levels 1-3 was designed for Labyrinth Lord but can be used with any old school dungeon-crawling RPG. It is a drop-in locale that can be played through in a few hours or in a much longer session...per the needs of your gaming group.
