Daemon Triumvirate

The Daemon Triumvirate is a group of three daemons in Valoria in Ultima IX.

This ancient group of daemons exists in three parts and can not be killed individually. When the Avatar visited Valoria, he soon learned that the knights there were being terrorized by the triumvirate, who were demanding that the knights hand over the Sigil of Valor. As the Avatar prepared to leave the city, the coward Eris betrayed the Valorian Knights and handed over the sigil to one of the members, but was soon slain after this betrayal.

The Avatar also learned from Meranthon about the 'Tome of Daemonology', which contained the secret of how to slay the daemon. It was revealed that all three daemons had to be killed simultaneously. The Avatar recruited Lambert and Artos to destroy the fiends, and together, they put the triumvirate to an end.
