Lutie is the Christmas town of Ragnarok. NPCs such as Santa and a snowman can be found here, along with winter/Christmas themed monsters and buildings. The entrance to the dungeon can be found in Lutie. To get to Lutie, talk to the Santa NPC at the top right building in Al De Baran. He will teleport you for free to the field outside of Lutie. The portal at the top of this field leads to the town.
