Shadow Play

[HG/SS] AU/AO: In this alternate timeline, Albus Dumbledore uses old research that he and Grindelwald came up with to craft the ultimate weapon to collect power and rid himself of enemies. His first two experiments failed him. His third did not—but what happens when it comes time to pay the piper? Who will rise, and who will fall? Not canon. NOPE! M to be safe. COMPLETE
