Church grims guard churches and punish those who would wish to disrespect it. They are said to ring the bells at odd times. A church grim could be created by burying a black dog on the North side of the church. A church grim can be summoned by writing the Lasabrjotur on the church and blowing into the lock, causing the Kyrkogrimen to appear.
Grims may appear as many different animals, usually dogs or goats. They can also appear as a priest in a brown robe. The grims will attempt to punish evil-doers who step into their churches.
