Selune first took interest in Mantea during the Primordial Era, where she took a guiding hand in the development of life in the realm. To counter the forces of her nemesis Shar and the deities of evil, she partnered with Njord who also held the world in high esteem and founded the Uddemiath, a council of divine powers intent on fostering life in the young realm. This relationship ultimately begat her four daughters who rose as shieldmaidens of the forces of good in the conflicts that culminated in the fall of the Uddemic era (-50 year from 1PA). At this juncture, Selune retired to the halls of Argentil in the Gates of the Moon, leaving her four daughters as stewards of Mantea. During the Lli-Nitha era that followed, her daughters asserted themselves as avatars of Selune, and established the version of Selune Worship that persisted through the subsequent eras.
Much of Mantean's understanding of the Goddess is through the works of Ton Serethil of Maunator. Ton was Netheril priestess who came to Mantea in the Perut Adraz era. An interplanar refugee from the collapse of the Netheril civilization, she escaped Toril through the Astral Sea arriving in Mantea in 174 PA. Establishing herself in the Kruterra empire in what is now the region known as Burmuth, she was bewildered to find a realm thriving with no knowledge or connection to her own homeworld. She devoted herself to researching the historiy and divine cosmology of HIstorical Mantea, becoming one of the few scholars to preserve the history and understanding lost in the Lli-Nitha period. Ton Serethil's, Canticles of Selune are widely regarded as the canonical source of Dogma and scripture for Selune and her four daughters.
While Elves devotion to Selune by name as a unified power is largely practiced by Elves and Druids, By contrasts, most other humanoids, focus on the four moons as her daughters and manifestations of the various elements of her domain across the world.
Sileah - The Swiftness. The youngest of Selune's children, Sileah is both the brightest in the Mantean sky and makes the quickest cycle. To the faithful, she is portrayed as an enthusiastic and vivascious young woman embodying the concepts of ephemeral beauty, mercurial grace and the flirtatious feminine youth. Lore surrounding Sileah describes her as the sibling of the four sisters most fond of their father Njord, and the first to intercede for mortals to the vast power of Mantea’s seas. Based on the story of her defeat of the Marauders of Kozarah, she is revered as a patron and protector of Coastal Communities, and ceremonial devotions to her commonly involve beachfront temples and reflecting pools.
Irah - The Severence. Selune’s third child is revered as the embodiment of Purity and inviolable feminine power. She is often portrayed as a stoic warrior maiden and the most calm measured and thoughtful of her siblings. Devotions to Irah focus on purification and fertility rituals, healing, and divine feminine archetypes. Lore of Irah’s influence on Mantea tells of her role in the keeping of seasons, the renewal of life and rebirth, and the removal of corruption. She is Lauded as the Champion protecting mortals from Lycanthropy, and intercedes to protect Manteans for the countless horrors of the night.
Malach - The Inscrutable. Selune's second daughter is the embodiment of the chaotic call of the wild, natural urges, unpredictability, the primal patterns of the world and the unknowable truths of nature, and keeper of the darker aspects of Selune's portfolio, madness, melancholy and chaos. Portrayed as a wild haired and recalcitrant daughter, her devotee's are renowned for fierce independance. She is often revered as the patron of those who reject civilization, hermits, and those that walk the borders of sanity. Her legends tell of her defeat of the Gnoll Hordes of Skoguria, and her protection of the Wood Elves of Ham-Nahzil. Of the four moon goddesses, worship of Malach is characterized by druids, ascetics who embrace riddle-like thought experiments and koans that lead to meditative breakthroughs from traditional thinking.
Eyre - The Sapeince. Selune's first born, eldest of Selune’s daughters is representative of the celestial body with the most distant and slowest orbit around Mantea. Her domain is the keeper of arcane mysteries, and is said to hold the keys to the passage to her mother’s domain in Yggdrasil. She is characterized as a mature woman, with a cold and aloof demeanor. Often called “The Ivory Queen”, lore of Eyre tells of her presiding in an inviolable temple palace, where supplicants assemble outside the walls begging for insights that are revealed only to the most deserving. Devotions to Eyre are most often performed as part of the most elevated ecclesiastical groups, mages and other arcanists and most of the canonical interpretation of her influence has little to do with the day to day life of mortals.
