Arcaelion (Moon)

Arcaelion, also known as Spheron I or Geometrica VIa, is one of the three moons of the planet Spheron and is named after the star of the same name. It is one of the planet's two smaller "starter" moons, the other being Kerithis, both of which formed along with Spheron. The starter moons are both one-fourth of Spheron's size, making them approximately half the size of Earth. Arcaelion is the innermost starter moon of Spheron and the innermost moon overall. It is sometimes known as the Dawnbreaker Moon, as it can be seen transiting Geo C, the red dwarf star that divides the inner system from the outer, on Spheronian dawns. Like the rest of the celestial bodies in the Geometrica System, Arcaelion was originally created by the angel Michael Clearwater using the Genesis ability.

Though it would be a barren, dead world on its own, Arcaelion is shielded from the weak stellar winds of Geo C by the enormous magnetic field of its parent planet. Arcaelion is therefore able to hold a breathable atmosphere, making it habitable. The moon's surface is very like that of Spheron and Earth, with plants, animals, water and relatively tame weather for much of its orbital period. For one fourth of its orbital period, Arcaelion is caught in the gravity and magnetic fields of the other moons in addition to Spheron, resulting in a period of intense magnetic storms in "danger zones" on the surface and "aurora zones" in the skies of the moon. The name given to this period of time is the "Season of the Metal Tricksters", as the storms cause electric shocks on contact with metal, cause metal objects to attract smaller ones to them, cause stunning auroras in the skies of Arcaelion, and can wreak havoc with technology. Arcaelion's sister moon Kerithis suffers from such storms as well. Being a starter moon, Arcaelion is tidally locked to Spheron, with one side constantly facing its parent planet. Both moons also orbit Spheron in a direction opposite to the planet's rotation.

Arcaelion is also host to its own biosphere, which, like all the other moons, is highly similar to that of Spheron, but includes a few species of plants and animals that are unique to the moon. It is designated as a tourist destination by the Spheronian government, and hosts resorts and other event centers. Arcaelion is also considered a nature reserve by some, and as a result is not completely Spherimal-inhabited. The moon is also a popular destination for Spheronian honeymoons.
