After they journeyed by boat to the Elven outpost at Drey Wood, the group found the entire garrison that had been stationed at the outpost dead—and the Reaper, who had killed all of them. They managed to escape by setting off down the river once more, but two of the Elven guards were run down and killed in the process. Wil realized that there must have been a spy in Arborlon, and that if the spy knew about Drey Wood, then it was likely their mission was known and they would be pursued the entire way. The party then goes to the Matted Brakes, where another two of the group are killed by an unknown massive creature. After escaping from the Brakes, the remaining group of five found themselves at an ancient Elven fortress named Pykon. The group made the decision to rest the night there, but the Reaper found them again and killed the final two Elven hunters. Wil and Amberle ran into the network of tunnels inside of the Pykon to try to find Crispin, who had gone into there to try to find a way out. Wil and Amberle finally lost the Reaper by destroying a bridge over a gorge, but they lost Crispin as well. During the battle, Wil failed to unlock the power of the Elfstones and believed that his human blood was blocking him from using them. He was resigned to not being able to use the stones anymore, and decided that they would just have to get along without them. The duo met the young Wing Rider Perk soon after, who agreed to take them into the Wilderun on his Roc, Genewen. He also agreed to fly over the Hollows every day for a week in case the duo had need of his help.
