The Cassalanters

The Cassalanters are nobles who live in Waterdeep. They invited the group to their mansion and revealed that they worship Asmodeus. Simon almost joined a cult of Asmodeus who operate out of a secret basement area. The Cassalanters made a deal with Asmodeus that transformed one of their kids into a chain devil, and the other two may transform as well if the terms aren't met by a certain date.

 * Terenzio: The son
 * Alzarina: The daughter.
