Catacombs of the Cold Legion

This is a dungeon for PCs of level 2 or 3. Three centuries ago, the immortal Cold Legion rampaged across this land but were finally halted at the battle of Nalrim. The dwarves of Nalrim defeated the horde and used elemental ice to freeze those evil creatures, imprisoning them in a specially prepared catacomb. However, the ice is beginning to thaw and this terrible army will soon be free. Someone needs to wrap up warm and insert the last ice chi into the heart of the dungeon.
