Prologue:
Harry lay in his bed. The Gryffindor dormitory had been nearly demolished during the war in the past few hours. He sighed. The twins were cut in half. Students had been killed. The marauders had been discontinued. Harry's mouth twisted into a strange mixture of a smile and a grimace. He was imagining Fred in the wizard afterlife, yelling at Harry 'Why didn't you tell me that Prongs was your dad? Or that Moony was our teacher? Or that Padfoot was Sirius? Or even that Wormtail was that absolute git who betrayed Prongs and Lily?' Harry rolled over on the mattress and buried his face in the pillow.
"Harry?" A voice called from the doorway. Harry looked up, a little bit startled. He was relieved to see Ginny.
"Hi. I was thinking of everyone who died." He said, a bit bluntly. Ginny walked over and squeezed his shoulder.
"Have you seen mum? I've been trying to find her. To tell her about Fred." She said, struggling not to burst into tears.
"I'll check," Harry said thickly through his own grief. He reached into the trunk. Suddenly he stopped. "Reckon it'll still work even though all four of the marauders are gone?" He asked her. Ginny shrugged. He reached into the trunk and withdrew a sheet a yellow parchment. The marauders map. When it was unfolded, Harry began to cry in earnest. There, in the middle of the parchment, were two words that would be displayed seemingly for eternity.
'Mischief Managed'
