Secret Lair of the Snowmen

The quest 'Lost Treasure of King Hundar' from Koris Deeprunner in Umbral Hollow takes you to the Secret Lair of the Snowmen in order to search for the king's lost treasure. The cave is full of level 15 snowmen which attack you in order to protect their secret lair. Among the level 15 snowmen are some other types such as Jack Frost, Freezie and a monk boss snowman. You must first find a Dungeon Key and then a Boss Key in order to reach the end of the quest. Talking to 'Beacon of Droknar' as you progress helps you to get points of favour with the dwarves. There are also pets called 'Wintersday Moa' in the caves.
