Plat (Pronounced like Splat without the S) is... well, it's Earth from another universe, serving as the main setting for Hero's Sandbox.
It is very similar to Earth in many ways, though with the noticeable differences of:
Being magical. Magic flows through every rock & mineral in the planet; the most powerful found in crystals, though even the common soil has power of its own. Sometimes the ground splits apart, hovering upwards as floating islands. Minerals being magic also explains the following:
Having two thin planetary rings.
They are collectively known as the Painter's Brush; due to the appearance of being like paint streaked across the sky.
Having a rainbow-coloured atmosphere.
As the planet & the atmosphere rotates; to inhabitants, the sky appears as different colours of the rainbow, depending on the day of the week.
Red skies = Monday
Orange skies = Tuesday
Yellow skies = Wednesday
Green skies = Thursday
Blue skies = Friday
Purple skies = Saturday
Pink skies = Sunday
It's magic, don't question it.
Being orbited by two pink Moons.
The larger, faster Moon is called "Splish".
The smaller, slower Moon is called "Splash"
Both Moons, as a pair, are casually known as "Splish-Splash". A more formal & ancient name being the "Nightmare Eyes". They're both ocean worlds.
Both Moons are actually about the same size, they just appear different in the sky because Splish is nearer to Plat than Splash.
Humans never existed; in their place are the Sculpturekind.
