The Frigid Cold of Despair

Publisher's blurb: Dwarves living on the moons orbiting the planet Myru have found portals suddenly linking all their moons to the Ice world below inhabited by white dragons, when before there was only the one portal linked to the dwarven battle-moon, Vahrnelm. Now under siege, the dwarves hired Giff mercenaries to help slow the white dragon incursion, but the party is needed to directly deal with the portal problem... and those that created it. A Four-Hour Adventure for Tier 2 Characters. Optimized for APL 8.
