『 The nameless world of a canvas, the entertainment of a Game. An ephemeral world meant to be forgotten. 』

The nameless world, that will be identified as UnderLethe in parallel with the Infernal river Lethe of forgetfulness found in Greek mythology's underworld, is a world believed to have been created by the hands of different entities soon categorized as the (primal) Gods of the World. from lands to lives, these Gods take the credit of all. Each holding rights to a species of their own doing, divided into two main categories, Ostermn and Ahnum. The world is composed of 5 continents, Monisclera (the White Lands), Pyarlais (Ardent Stars), Thyloss (the Depths), Ourhales (Lands Above), and Aargeon (Center point). There is possibly a 6th called Erimostroma (the Desolated Layer), but as the name would suggest, not a place being visited often.

This world is heavily based on faith, on beliefs, and on the concepts being held, and all these beliefs and concepts are what define Gods. Said 'Gods' are divided into different sections, like a hierarchy. At the very top are the Primal Gods, who were at the very beginning of the world's creation. Next come Gods (sometimes called Lesser Gods), the Gods that are considered to have the same rights of creation as the Primal Gods and/or as powerful, but that only manifested themselves long after the game (that will be mentioned after). Then comes Deities, beings that have acquired a 'divine' status, quality, or nature; they are, in the majority of cases, worshipped as a divinity, or the Avatar of a God. They are believed to be immortal... Or have conditions to die.

In this world, Gods each choose a 'player', a living among their own creations. Among all Gods is 'a' 'Scapegoat' for others to aim and find out.
To find each other out is the main action. The Gods playing are known, but the players they choose aren't.
