Editing MidHammer 40,000: SM Chapters (section)

====Religion====
The Fortunate Sons are part of the wide collection of Promethean/Syncretic cults called "The Cult of The Dauntless Few" or "Impavidae Cult." Unlike the other Gullimanders who are usually Ultramarines pretending to act like Salamanders, the Fortunate Sons are Salamanders pretending to be Ultramarines.

Despite being cut off from the Promethean cult, the Fortunate Sons felt a close tie to their estranged Genefather. They were able to find a supportive Spiritual Liege in the infamous "Rubber Stamp" Holy Seat of Laphis when joining the Aurelian Cult. They are still not very religious and their specific order is effectively Vulkan's promethean cult with a thin Ultramarine overcoat. 

The Fortunate Sons refer to The Aurelian as "Uncle Bobby," Uncle being an honorific for Thamhyusden, an ancient diety that was worshiped by Catachan's Ancestors. Likewise The Queen Mother is referred to as "Miz Blue Mam," and The Emperor of Mankind is "Mister Bossman," and is sometimes given the honorrific of their ancient diety Thamhyusden (Lord of Earth). Vulkan is still referred to as "Papa Vulkan," despite him wanting nothing to do with his wayward children.
