Magic: The Gathering: Invasion Cycle Series by J. Robert King

The Phyrexian nightmare begins. Dominaria faces its biggest threat -- an invasion by its greatest enemy, an attack planned for eons by merciless foes. No one is exempt from their terror. No land is safe from their onslaught. In the shadow of the Phyrexian horde, Dominaria has but one hope -- the Weatherlight and her crew. The time has come to defend hearth and home from invasion.

The first wave is over, but the invasion rages on. In the midst of an all-out war, the ground shifts and moves. Milliions upon millions of invaders appear out of nowhere as the artificial plane of Rath overlays Dominaria, covering the natural landscape with the unnatural horros of Phyrexia. There is no rest for the wicked.

The end is near! Phyrexian plagues and shock troops have taken their toll. The final stage of the invasion has begun, and the dark lord Yawgmoth himself plans to cross over into Dominaria to claim his prize. With time running out, the battered heroes' last hope to save their home lies in an ancient, untested weapon, a jumble of artifacts known as the Legacy. Bear witness to the apocalypse.
