Long ago, every planet in the Solar System was home to life — and each civilization had grown powerful in its own way. Then the Sun entered a new era with a catastrophic explosion that burned every planet but one. Earth became the only habitable world in the system, and all surviving races converged on it. They used their superior power to carve out territory, subjugate the comparatively weaker humans, and reshape the planet according to their own priorities. Into this world were born three sisters — gifted with the ability to copy the powers of others — who have decided it is time for humanity to take back what was taken from them.
