Heliopolis

A small "pocket" dimension adjacent to Earth; an interdimensional nexus between Heliopolis and Earth exists somewhere in Egypt. Heliopolis is a small other-dimensional planetary body whose nature and physics are different from those of planetary bodies in the Earthly dimension. Heliopolis serves as the home to the Egyptian gods. Heliopolis resembles the realms of Asgard and Olympus. This relatively flat asteroid-like landmass is suspended in space, and is surrounded by what its inhabitants call “the Abyss.” It is not known if Heliopolis's source of light and heat is Earth's sun, or a glowing ball of light dissimilar to a star in most of its properties. Unlike Earth, where the force of gravitation radiates from the mass of the planet, Heliopolis has gravity, which apparently radiates from some point or object beneath the suspended landmass. Consequently, there is a topside to Heliopolis, upon which beings can stand.

There is apparently some force that keeps the bottom and edges of Heliopolis's landmass from eroding away. This force also prevents Heliopolis's atmosphere from escaping. Heliopolis is surrounded by what Heliopolitans call "the Abyss," which may be similar to Asgard's "sea of space." The exact nature of space in the Heliopolis dimension is unknown.

While the gravity of Heliopolis is roughly analogous to Earth's, common Heliopolisian matter is considerably denser than Earth's on the average. Consequently, a chair made of Heliopolisian wood would be more massive, heavier, and more durable than a chair made of analogous Earthly wood.

Heliopolis is linked to several other dimensions. The dimensional bridge between Heliopolis and Earth leads to somewhere in Egypt. There is also a nexus between Heliopolis and Abydos, the realm of Seth.
