Material Plane

The **Material Plane**, or sometimes **Prime Material Plane**, is the plane of existence in which the world of Aegirrim exists.

### **Satellites**

Aegirrim has three moons:

* **Cidla** : close to Aegirrim and appears white in color and large in the sky. It has a 30-day cycle during which it waxes and wanes.
* **Desoladar**: the reddish-brown color moon. It takes either half a year or approximately one full year (365 days) to complete a rotation and thus is only visible in the sky for half the year.
* **Lun**: close to Aegirrim and appears purplish-blue in color and slightly smaller than Cidla in the sky. It has a 60-day cycle during which it waxes and wanes.

### **Sun, stars, and constellations**

Aegirrim rotates around a star at the proper distance to allow life on the planet's surface; this star is called Oro, often associated with the Pelor, Lathander, and, to a lesser extent, with Sarenrae.

Moreover, in the night sky there are numerous visible stars, much more distant, which due to their arrangement in the Astral Sea form constellations with associated stories in different cultures of the world.

### **Other planets**

Celestial bodies can be seen in the night sky that might be mistaken for stars but are actually planets, close enough to Aegirrim to be seen without a telescope. It is believed there are 7 planets in total orbiting around Oro, each with their own unique characteristics, mythos among Aegirrimian society, and satellites.

Outside academic circles there are those who are unaware of the existence of these planets, and assume that Aegirrim is the only one.

## **Other Prime Material Planes**

As of 3E, 1048, only the most expert astronomers of Aegirrim have learned that there are numerous worlds on the Material Plane, although they haven't devised a way of traveling between them.

Outside of Aegirrim, there are several races that can navigate the Astral Sea aboard various vessels such as Nautiloids or Spelljammers.

## **Relationship to Other Planes**

In some places, the barriers between the Material Plane and other planes become thin or are simply punched through. Some rifts are stable for long periods: there are settlements around long-lasting rifts with the Elemental Planes, and known portals to the Feywild, for example. The barriers regularly become thinner during the annual solstices. The barriers become especially thin under a celestial solstice.

Once opened, rifts can be widened or they can be sealed. Long-term doorways can be established between planes and realms, starting with anchor glyphs and building a permanent enchantment around them, similar to building a permanent *teleportation circle*.

### **Echoes of the Material Plane**

#### **Feywild**

*Main article: Feywild*

The Feywild, also called the Fey Realm or Plane of Faerie, overlaps the Material Plane. It is rumored there are several entrances to the Feywild located with the Wilds of Esvadell, but only the elves who reside there know for certain.

#### **Shadowfell**

*Main article: Shadowfell*

The Shadowfell, or Plane of Shadow, also overlaps the Material Plane.

#### **Ethereal Plane**

*Main article: Ethereal Plane*

The Ethereal Plane overlaps the Material Plane, but they are somewhat out of phase with each other.

There are several spells, items, and even innate abilities allowing creatures on the Material Plane to interact with the Ethereal Plane. Creatures who use the drug Night Whisper can see into the Ethereal Plane out to ten feet; the spell *True Seeing* allows the target to see 120 feet. Creatures slathered in *oil of etherealness* enter the Ethereal Plane for an hour. The spell *Blink* allows the caster to enter the Ethereal Plane for short periods and move up to 10 feet to a different position in the Material Plane; a phase spider or an incubus can switch between the Material Plane and Ethereal Plane at will.

### **Inner Planes**

#### **The Elemental Planes**

The Elemental Planes intersect with the Material Plane. During the Upheaval, the ancient Primordials were sealed away in their respective Elemental Planes by the Gods of Aegirrim in order to stop the destruction of the Material Plane and all the life within it. The locations where the Primordials were sealed has been lost to time, but there are some rumors and theories as to where they might be:

* **The Elemental Plane of Water** is rumored to be contained somewhere in the Risen Reef off the coast of Elodria.

### **Astral Plane**

*Main article: Astral Plane*

The Astral Plane, or Astral Sea, separates the material world from the Outer Planes and beyond, and had to be traversed by specially built vessels before the discovery of spells like *plane shift*. The Astral Plane, or Astral Sea, contains gateways to other planes and is home to the illithid and githyankiamong other creatures.

### **The Divine Gate and the Outer Planes**

At the end of the Upheaval, the Divines and Malefactors erected the Divine Gate, a sort of lattice through which gods cannot pass, between the Material Plane and the rest of creation. Most people call this event the Banishment.

It is theorized that the Gods themselves could break the Divine Gate through a unanimous effort, but that would ensure almost certain destruction of the Material Plane.

#### **The Abyss**

*Main article: Abyss*

The Abyss is the home of demons.

### **The Far Realm**

*Main article: Far Realm*

The Far Realm is another dimension that connects to the Material Plane in some places, often in the depths of the Underdark. Aberrations from this realm may have been called to the Material Plane by one of the Malefactor Gods such as Tharizdun, or may have crossed over through rifts opened by the vast forces released in the Upheaval.
