The Saradominist Order of Paterdomus is an unofficial name given to a religious order that occupied Paterdomus, a temple constructed along the Misthalin - Morytania border. The Order was largely destroyed in the Year 169, during the Occupation of Paterdomus. Paterdomus has since been controlled by the Zamorakian Order of Paterdomus, but has since been reclaimed.

Only three known members of the order survived the occupation: Hiylik Myna, who fled but later returned under the protection of the Misthalanian Mercenary protocol; Ulizius, who now guards the entrance to Mort Myre; and Drezel, who was captured but later freed. Drezel and the priest Ivan Strom were able to occupy the lower levels of the temple undisturbed.

During the Battle of Paterdomus, the final battle in the Sanguinesti Liberation War, the temple was reclaimed by an adventurer and served as the battleground between the armies of King Roald and Vanescula Drakan. Drezel was killed during this conflict, leaving Ivan Strom as the only member of the Order present at the temple.
