Vast Universe.
A boundless gigantic wall floats in the dark, void space ahead.
Perhaps calling it a wall is not quite appropriate, for at least walls have visible limits, but the expanse before us is limitless, its end unreachable even by the detection means of a Level 3 Civilization.
Moreover, the scene in front is not impervious like an ordinary wall; instead, it is a material band formed by the convergence of countless interstellar materials. Despite the immense and incalculable amount of material, it is not tightly packed like a wall, with many spatial gaps allowing faint light to shine through.
From afar, it appears as if the once mighty wall of the Universe has been cracked by a supreme force, riddled with densely packed cracks and openings of various sizes, and the faint light piercing through these cracks endows it with a grand and mysterious aura!
