Rafire was frustrated and angry that Lord Rehare let Mark away, the belt of greater will was too valuable an asset to let it be in the hands of one who was clearly not from the forest, and one Rafire didn't deem as worthy.
In the past, Rafire had sent men after men to go into the temple and seek its treasure, but nobody came back and once rumours of the man-eating temple began, Rafire realized that he couldn't continue to send men to die for nothing, especially when he wasn't willing to risk his own life. He convinced himself that it was just a silly legend those before him brought up, and that they were none the wiser. He had given up. Then a few years later, a being that he hadn't seen, whether it was in books or in person, had the belt to himself.
