One of the first gods to exist was Serenox, also known as the Weavemother. Known for her spidery wit and intelligence, she was known as a storyteller and poet who could weave together entire histories. She is revered as one of the most important gods in the origin stories of the world, credited with weaving the initial fabric of the cosmos and threading the stars into the positions they hold today using her starloom. However, she was killed by Saenus during the Omniborn Crisis. It's said that Serenox 'punished' Saenus by naming her as the successor goddess.
She was known to be the consort to Deltus, the primary god of the elves and her brother. Before the formation of the greater pantheon's mythos, the fey saw them as the Day Father and the Night Mother, the diurnal and nocturnal guardians belonging to the Seelie and Unseelie respectively. Many things in the modern day are attributed as sacred to her and sanctified in her embrace, such as moonsilk, starmetal, or silvermilk. Followers pay homage through rituals involving intricate weavings, using cosmic patterns and starlight.
She was created by her parent, Elder Mekalus, alongside her siblings Jakuna, Sigmus, Deltus, Moros, as well as all Angels including Krros, Vertum, and Mutrev. Deltus and Serenox had a single child, Gunian, although the details are different depending on who you ask. Some whisper that Dradus, the cunning lizard god of luck, shares Serenox's lineage bearing her trickster nature and dominion over fate. She also had a daughter, Nosos, with Krros. Some Eqosi revere her as akin to their primordial Lunaa, while the Lunar faithful perceive Arryestria as either Serenox's offspring or a celestial reincarnation. The tears of Serenox are another name for the asteroid belt in between Abmarah and Arrai.
Deltus and Serenox have a key role in the creation story of the Shadowfell as well. When the witch Morgariel was trying to ascend as a dark goddess, the armies of the Seelie and some Unseelie intervened led by the two gods. With the gods commanding the battle, the witch's forces lost, and the spell was interrupted. With her powers, the lady Serenox cut off the half-corrupted half of the Feywild, and essentially created the Shadowfell. Lord Deltus bound Morghos in great divine chains, sealing the witch away within the heart of this new Plane of Shadow.
Originally venerated as the patron goddess "Epsilus" of the Moon Elves, despite many positive aspects Serenox as a goddess was respected with fear. The night was terrifying and she was its personification. Despite being so important to all elves, almost all would rather worship Deltus or Jakuna primarily. The elves who worshiped the night became increasingly insular over time, and legend whispers that Serenox deceived her devout Moon-Elf adherents into rebelling against the budding Aeteria. For this betrayal, Deltus excommunicated the moon elves who followed Serenox and didn't favor him, and banished them to the Underdark never to see Serenox's night sky ever again and be forever severed from her celestial embrace. The transformation of these Moon Elves into the Drow is shrouded, either seen as Serenox's blessing or Deltus' curse. Around this time, depictions of Serenox switched from the pale skin of the moon-elves to the dark skin of the drow. As such, the legendary artifacts linked to Serenox such as Moonshade and Rûdheryn are of both Moon-Elf and Drow origins, as both races respected her moonlight.
Serenox is known to have perished at the hands of Saenus during the Omniborn Crisis, when the Omniborn directly tried to challenge fate itself and rewrite the stars in their favor. This unprecedented cataclysm spurred a rare unity between Drow and High Elves, albeit fleetingly, against the common threat. After the war, Saenus was forced to take on the duties and powers of Serenox, and became the new goddess of the night. It's said that this punishment was decreed by Serenox herself who saw the good her killer would do in the future.
Staunch worshipers among the Drow maintain vigil, awaiting Serenox's return, holding onto the cosmic threads of hope for her eventual rebirth. She was the chief goddess of Môrism, and is still mourned to this day by the Mourning Court. The Veiled Queen of the Court is considered to be the spiritual leader of the faith, her consecrated bloodline believed to have the last remaining silk weaved by Serenox herself.
Though she is long dead and all her old followers know not to worship one who would never reply again, she is still deeply respected in elven and fey cultures.
