Mieli

Mieli, Meferi in Draconic, was the creator god of nature. During Creation, Mieli was responsible for crafting plants, climates, and ecosystems across Morn.
Mieli no longer exists as a single god. During fighting between the creator gods and interloper gods, Mieli was split in two, becoming Silvanus and Morrigan.

Warm-blooded Pantheon

In the warm-blooded pantheon, Mieli was the creator god who crafted the ecosystems of Morn. During creation, Mieli moved their realm, the moon, to be close to Morn so that they could watch over nature. The moon kept the ocean tides flowing and supported the cycle of nature.
When the creator gods fought with the interloper gods, Mieli was badly wounded. Rather than dying, as Mortus had, Mieli instead split into their two aspects. They became Silvanus, the side of nature that brings life, and Morrigan, the side of nature that brings death and decay.

Draconic Pantheon

In the Draconic pantheon, Meferi was an emerald dragon. They are not usually depicted as they are not actively worshipped, however the few depictions there are of Meferi show their wings spread with membranes depicting lush scenes of nature.
During creation, Meferi created the moon to watch over the original four dragons. When the creator gods fought with the interloper gods, Meferi split themselves into their two aspects, Zagal and Erregal, so that they would be twice as strong. However, each of their two aspects were only half as strong as the other gods. They were gravely wounded in the fighting, and in their weakened states they could not return to their own realms. Instead, they became the two moons of Morn, forced to remain on the material plane.
