The Phantasmoon, also known as the Moon of Elation,[2] is an imagenae resembling a moon that appears in the skies of Planarcadia. It is the namesake of the Phantasmoon Games, and plays a key role in them.[1]

Overview

The Phantasmoon is an imagenae, an intelligent being created from humanity's acts of fiction that prolongs its existence through the power of people's imagination and attention, also known as Wishpower. Regardless of the time of day, the Phantasmoon can always been seen hanging in the sky.[1][3]

According to legends, it was the first imagenae to be born after Aha painted a Phantasmoon across the skies of Planarcadia. Drawn by this spectacle, eight Mourning Actors presented stories so shocking and extraordinary that they hoped to earn an audience with Aha. Their performance marked the beginning of the Phantasmoon Games.

Since then, whenever the Phantasmoon waxes full, the Phantasmoon Games commences.[1]
