The Simmering Tooth is a large beast deep in Lavv Cave, a massive cavern in Alvalpa. It is a blob of gooey molten liquid that takes up almost the entire cave. Its only other notable feature is its huge mouth lined with dull teeth. The Simmering Tooth hibernates within the cavern for most of the year. One week of the year, it will come out of the cave to feed. Explorers who are able to get into Alvalpa like to visit during this time to study the blob. They have to keep their distance so they do not get consumed by the blob or burned by the scorching liquid on its body.
