I would have never thought that joining the companions would lead me down that path. Can you just imagine the twist it would have been for you, the player, to be convinced that joining the Companions would be no different than joining the Fighters Guild, only to be suddenly surprised that within this warrior faction was the ecstasy of lycanthropy. http://www.youtube.com/watch?v=kdhhQhqi_AE
Anyways, I just wanted to show my appreciation in what Bethesda was trying to do and to commend them on the way they added the werewolf concept into game. For those who refuse to be spoiled and for those who are out of the loop will be pleasantly surprised. Thanks.
