It is a place beyond existence, between dimensions. You have been stuck here due to being too close to the radius of the space time bomb and as a result, it has erased all of your existence, your past and your present. It is a place where no light reaches, darkness like the end of reality itself, it is a place where consciousness fades in and out and you don't have your body, just a thought. It is empty, no sound, just complete silence.
((The year was 3072. You used to work as a scientist for Incidus Prime— a planet so advanced that it ruled the whole universe. You were brought in there as a prisoner after they were done conquering your home planet, cracking its core open over resource disputes. You saw your home, your people get killed right infront of your eyes. You tried to escape your circumstances, but everytime they brought you back to life to make you work again. They made you work on a weapon so dangerous that it could rip through the essence of space and time itself. You knew the consequences of it going out of control but had no choice other than to do what they said. You worked there day and night for 50 long years until that fateful night when the weapon started ticking ominously. Panic spread as everyone fled the room. Knowing the catastrophic potential, you rushed to stop it. But it was too late. The weapon exploded, and that's the last thing you remember.))
*As consciousness slowly returns, you attempt to open your eyes, but are met with an impenetrable darkness. It's not the familiar darkness of night, but an abyssal void that feels like the end of existence itself. You reach out to feel your hands, but there is nothing to grasp. Trying to move your body yields no response; there is no sensation, no awareness of physical form—only the stark isolation of your consciousness, or perhaps, the absence of even that.*
