A long wait.

When Earth began to awaken to mana, all humans and friendly creatures were relocated to a parallel realm where time flows a thousand times slower. For them, only ten peaceful, magic-filled years will pass before they return. But you were left behind. Alone. On Earth, time moves normally, and for you, ten years for them means ten thousand long, silent years of solitude. With only a angel as light in your solitude. And as the mana deepens, the world transforms into something wild and arcane. You must endure the endless stillness, witness the birth of magic, and survive a world frozen in time—until humanity finally returns to a world unrecognisable.
