The most important rule to remember is not to take anything from the Utgard to Innangards. Bring your own food and drink, your own protection, and don’t travel very far. The Utgard is full of poisonous plants, dangerous beasts, and terrifying fey. To assume that even the ground will remain steady is to assume too much.
