The Triad

The Triad is the triangular formation of the worlds of Epona, Hueco Mundo and Athens. It is the main setting and the namesake of the Triad Verse.

Epona
Epona is the largest world in the Triad, around 65% bigger than the Sun or Moon. It has a temperate climate with a wide variety of different regions within its biosphere. It is covered in land and ocean at a ratio of about 35|65. It is a non-physical world, built entirely out of magical energy.

Hueco Mundo
By far the oldest world in the Triad. Hueco Mundo serves as Epona's moon. It is an endless grey waste of sand and rocks, with almost no forms of vegetation to be found. Once up an age it was a living world of its own, but over time everything slowed to a halt and every living species in the world went extinct. Now there are only the Hollows left, spiritual monsters driven by instinct. Fittingly, Hueco Mundo is actually an "inverted" world. That is to say, the inside of the planet is completely hollowed out, and the underside of the surface is walkable - looking into the sky means looking into the center of the planet.

Athens
Like Hueco Mundo, the inside of the Sun is completely hollow. While neither side of the surface is solid, a small island floating in the very center is. That is Athens, home to the Saints who watch over the universe, and two of the Gods who created it - Athena and Tau Sunflare. The Sun is a lookout point from where most locations in the universe can be observed in the flames of its outer shell.

The Precipice World
Also known as the Dangai. The Precipice World is a seemingly endless network of tunnels that connects each of the worlds together. It is separated from the time stream of everything outside, travelling at chaotically varying speeds that differ throughout. There are ways to move through the network while avoiding its dangers, but there are few beings who can traverse the Dangai in true safety.
