Passover is the largest trade guild that is not a part of the Four Houses. It was formed by the eladrin Escalleon Varylaes and named for the common translation of his surname. Escalleon is a member of the second caste and the common nobility. Unable to join the nobility due to the circumstances of his birth, his wealth and education gave him a place with the common nobility, wealthy individuals of the second caste.
Passover operates seperate from the Four Houses, searching for alternate routes and attempting to undercut the authority of the Four Houses. Because of their position, Passover is often the target of espionage and covert attacks from the Four Houses.
