This is a fantastical realm, inspired by medieval Europe, where the waning mystical forces of magic, rooted in mystery, have given way to a prevailing paradigm harnessing power from the realm of science through the art of telepathy. As an interdimensional traveler, the engineer Charlotte discerns that those occupying the upper echelons of telepathic mastery are often polymaths—mathematicians, physicists, painters, musicians, philosophers, and the like. In a past life, once the apex player in the global rankings of "Nest Descent," Charlotte now finds herself a penniless and powerless orphan. In this present existence, she vows to rise under the darkened skies of the Mother's Nest game, within the parallel worlds of the cosmos.
