Porter's Bar combines religious elements brought by refugees from an Asian culture, with the religious beliefs of the Wen and a unique version of Ancestor Worship practiced by the Royal Family. Arth, the Wen demi-god, is the city's patron.

Unlike most noble families the Royal Family of Porter's Bar train all of their members as Clerics in the religion of the Royal Ancestors, unless they are unable to complete the training (Characters MUST have a wisdom of 12 to train as an Adept or 15 to train as a Cleric or Inquisitor). They may then go on to become a functionary of the Royal Court and get special privileges, such as better better jobs and living conditions. They automatically gain the Scaly Kind domain as part of their training, those characters (clerics) who gain a second domain may take a second domain from the Repose(ancestors), Healing, Knowledge or Community domains. Many multi-class as either Experts or Warriors after a level or two, and go on to form the core of the administration and royal guard. The best multi-class as a Sorcerer with the Aquatic Bloodline, showing that they have inherited powers from both their paternal and maternal family founders. These are the characters who could go on to become the next ruling prince/princess. As a faith that does not have a deity as its patron, the Cult of the Royal Family's Ancestors can only grant spells up to third level. Membership of this cult is only available to members of the royal family.

Many other families have small shrines in their homes to help them remember their own ancestors, although this is generally linked to the Temple of Yamara, and does not grant any special abilities.

It needs tweaking, but there is a better analysis of the cult here.

Many of the residents have Wen ancestry and some are almost full blooded Wen, so the core philosophies of the Wen have some following throughout the city state.

However, for most of the city's residents Yarma and Arth have become the most significant gods in the pantheon There are temples to both demi-gods in the city, where clerics will pray for intersession on your behalf. Yarma looks after the funeral rights for the dead, and Arth provides help and healing for those in need. Arth has become the patron deity of the whole of Porter's Bar.

Many of the original settlers were seamen who were followers of an Oriental deity called Shan, who is said to be a master of the seas and winds. Less forgiving than the Annite deity Zalina, Shan is the patron of fishermen and sailors.
