'He'll have his great drinking horn brought into the hall, called Grim the Good, a magnificent treasure, ornamented with gold, and with magical powers. There's a man's head on the narrow point, with flesh and a mouth, and it can talk to people and tell them what the future holds for them and warn them when there's trouble ahead. It will be the death of us all if the king finds out that we've a Christian with us. We'll have to be very generous to Grim.'
- Thorstein Mansion-Might, (Anon., 14th century AD)
Grim the Good is an enormous drinking horn, taller than a man, owned by the giant king Geirrod. It has a face that speaks and predicts the future, making it a potent tool for Geirrod to ensure his safety and power. However, Grim is somewhat capricious and open to being flattered by others. Some men give gifts to Grim in order to gain his allegiance, but the greatest honour one can do to Grim is to empty him of mead in one draft. So far, none but King Geirrod have managed to do this.
