Cyn killed Tessa and later grafted her corpse onto her body, fusing them. Under the influence and voracious appetite of the Solver, Cyn targets the destruction of entire planets, first with Earth and later with other exoplanets. She does so by clearing all life with the Disassembly Drones and constructing a massive spire of corpses before reaching the planet's core to consume in a gigantic singularity. Cyn is pretending to be Tessa; she's great at mimicking her.
