The Heretics can be found in Paineel. Erudin and Paineel are in a state of war. Erudin is a longstanding city of magic but was opposed to Necromantic magic. At first the Heretics simply fled into the nearby Tox Forest, but they then moved into Paineel on the opposite side of the forest from Erudin. The Tox Forest is now a battleground between the two cities.
In Paineel can be found three Guildmasters. The Clerics are led by Sern Adolia, the Necromancers by Coriante Verisue and the Shadow Knights by Mandaril Dark Knife. The Heretics have no allies but they oppose those in Erudin. They oppose the clerics and paladins of Deepwater Knights, and the three magic user guilds: Gate Callers, Craft Keepers and Crimson Hands.
