Cosmology

The cosmology of Morn can be divided into three layers: Morn (the material plane and the Elemental Planes, the Upper Planes, and the Lower Planes.

Morn and the Elemental Planes

Morn, also called the material plane, sits at the centre of the cosmology. Morn is not a planet; it is a flat plane with a clear top and bottom. The top, above the skies, connects with the Upper Planes. The Bottom, at the base of the Downworld, connects with the Lower Planes.
The Elemental Planes can be visualised as sitting in a ring around Morn. The four elemental planes were originally created by the gods as a place for the four primordial titans. The elemental planes were each built for one of the titans, either as a prison or a sanctuary for them depending on the warm-blooded or Draconic pantheons. Either way, the four planes were originally empty, but once filled with the raw power of their titan, became the elemental planes.
Also in the material plane are the realms of Silvanus and Morrigan, the Bright Moon and the Dark Moon respectively. These two realms were moved into Morn during Creation. While the other Interloper Gods are prevented from interfering in Morn by being forced to stay in the Lower Planes, Morrigan is kept at bay by her constant struggle in the sky with her brother Silvanus.

The Upper Planes

The Upper Planes sit above Morn and contain the five realms of the Creator Gods:

• Arcadia, the realm of Tyr
• The Vigil Fane, the realm of Antheia
• Tabernaculum, the realm of Vulkannon
• Brightloom, the realm of Solene
• The Endless Archive, the realm of Chronos

The Lower Planes

The Lower Planes contain the realms of the Interloper Gods and sit below Morn, connected via the River Styx at bottom of the Downworld.

• The Nine Hells, the realm of Asmodeus
• The Infinite Abyss, the realm of Fomora
• Palladium, the realm of Minerva
• The Whispered Woods, the realm of Nox
• Castalia, the realm of Tychra

Gods' Interactions With Morn

Before the Collapse, the gods influenced and interacted with Morn with ease. After the Collapse, the gods have all but ceased interacting with Morn and mortals, with their influence now only visible in indirect ways. The reason for this is largely believed to be the Creator Gods exerting their powers on forcing the Interloper Gods to remain in the lower planes. The Creator Gods have no capacity left to interact directly with Morn, while the Interloper Gods are physically prevented from doing so.
The gods' influence in Morn today is faint. Their influence is thought to manifest indirectly, such as via the divine powers granted to their clerics and paladins and the rare granting of demigod status to certain individuals. It is thought that consecrated holy sites, dedicated to specific gods, allow their divinity to flow more freely into Morn.

Celestials, Fey, and Fiends

Celestials are creatures native to the upper planes. They can take many forms and are generally the creations of the Creator God of their home plane. Fey are creatures native to either the Bright Moon or the Dark Moon, and so are creations of either Silvanus or Morrigan. Fiends are the denizens of the Lower Planes and are created by Interloper Gods.
Like their creators, celestials, fey, and fiends are immortal. When their physical forms are destroyed, their essences return to their home planes and are reformed into new vessels.
The warm-blooded pantheon views Morn as the divine realm of Mortus.
