The Leviathan Chapter is the Arkrist chapter of the Casque & Gauntlet. In 8793 SE it was led by Marshal Montrose ‘Monty’ Tibideaux, who received contracts from clients, matched work to available adventurers, and maintained relationships with city officials and other potential employers.

The adventuring group later known as the Drakefire Phalanx first came together through the chapter on 14 Yilaver 8793 SE. Its earliest contracts included the investigation of the Goldreach Estate, and Montrose continued to act as an employer, broker, and source of leads as the group began taking work beyond Arkrist itself.
