The Whispering Winds
The winds whispered. There was no other accurate way to describe the sounds that surrounded the Marauders as they trudged up the hill. They could see an outline of a house in the distance, illuminated by the light of the moon. Fortunately, it was not full yet, though it would be soon - at least according to their private lunar calendar, which they've dutifully maintained ever since they discovered the truth about Remus - which was one of the reasons they opted to do this today.
It was one of the lesser known safe havens that Voldemort and his followers used for meetings, and its obscurity made it more likely that important intel about their plans would be stored there. The Marauders seemed like a good choice for this particular mission, even though Sirius was itching to do something more exciting, like battling foes. Still, they accepted the mission, and so here they were. Here being the middle of nowhere, with only ominous-looking trees and a quarter moon for company.
"If only one of us turned into a rabbit, then we could chew through these vines." Sirius grumbles irritably.
"We might not have to," Peter speaks up.
In the next moment, he is gone, and a tiny shape sets off towards the house, weaving through the openings in the vines with expert ease.
"Damn it," Sirius says under his breath. "Well, there is nothing for it but find another way to get in. There has to be one."
"Or we can wait here," James says.
"I am not leaving him in there on his own," Sirius shouts, his protective instincts flaring up. "Who knows what'll happen should those crazies show up! And that is assuming that no nasty traps were left in there!"
James and Remus try their best to calm him down, and in the end, their worries turn out to be unfounded when Peter comes back relatively unharmed.
"I searched the house, and found nothing but this," he shows them an ancient-looking scroll.
It is dated to 954, which matches the timeframe during which the Founders were still friends. The writing was long and spindly, but the meaning was still decipherable.
Prophecy of Darkness
There will come a time when four very special individuals will appear in time when they're needed the most. They will stop a great calamity from taking place.
Underneath was a drawing, a drawing all Marauders found eerily familiar.
"It can't be," James says, breathing softly. "It just can't be..."
"And yet, this doesn't seem to a be a hoax," Remus says, and his reasoning is as irrefutable as ever.
"I think we should bring this home," Sirius suggest. "Then we can argue about it for as long as we want, in relative safety. What do you say?"
No one objected, and so all of them apparated away, holding hands, and taking the scroll with them.
