The owl was short and unsigned, but it caused a chill of fear to run down Ginny's spine anyway, when the owl landed on her desk. She was the only Auror in the main room, the rest of the Aurors on duty were either out on routine patrol, or sparring in the basement. She wasn't sure where Percy was, but she couldn't wait to find out. She sent a quick owl to him, and a Patronus, and hoped that it found him in time. But she couldn't wait for instructions before acting. She had to consider this a legitimate threat, and act as such.
She set off the internal alarm that would let the other Aurors in the building know there was trouble, and as she waited she sent a Patronus to Neville, Harry and Remus. The one to Neville probably wasn't strictly protocol, but she wanted him to know where she was. She was quick and to the point, letting them know where she was and to come as soon as possible. She was shocked for a moment at the form her Patronus took--it was an Archer, when before it had been a lion. Knowing she had no time to wonder what that meant, she pushed the thought from her head.
By the time the Patroni had disappeared, the rest of the Aurors had arrived. There were five of them all together, and Ginny had no idea if that was enough. Cormac was there, and she told him to gather the rest of the Aurors and send a second force of ten Aurors behind her as soon as possible. He nodded, and she was scared he intended to be one of them. There was no time to remind him of his leg, as she and the other four Aurors on duty headed to the Apparition point.
It didn't take long, and before they all Apparated Ginny reminded them that they should be at the ready, but be prepared for any eventuality.
They appeared on the outskirts of Godric's Hollow, and as soon as she was able to see ahead, she knew they were in trouble. Rodolphus Lestrange was striding down the hill, flames from Harry's old home framing his silhouette. There were only five Aurors, against who knew how many Death Eaters, but hopefully, help would be arriving soon.
