Okay, I killed the Will-o-Wisps though I don't know how or what worked. Anyway, I'm back at the beginning of the fell wood and I need to find the ghost that's silent.

Anyone know the way?

The gost that is silent(Kyosti's spirit) is not in Fell wood. When you kill the Will-O-Wisps, talk to the guy at the beginning of the woods and he'll tell you stuff. When you ask him about a silent spirit, he'll say there is no solent spirit in the woods, but that he saw a specter lingering next to a big block of stone infront of the woods(Limha's area). Go there, talk to him, you convince him that he can talk and then report to Kruttu.

Yeah, I got it. Thanks.
