Skyline Echo

The Skyline Echo phenomenon began after the dimensional experiments of 2157. The city exists in a state of quantum superposition, visible from multiple realities at once. Residents report seeing "echo buildings"—structures that flicker in and out of existence, sometimes solid, sometimes translucent. These echoes follow patterns that scientists are still trying to understand. The effect is most pronounced at sunset, when the boundary between dimensions grows thin and the city seems to multiply across the horizon.
