Hathaway.
Marvin didn't think that he would hear this name in the Wilderness Hall's Autumn Hunting Ground, and furthermore from the mouth of an old monster who had lived for countless years.
At first, he thought that he had misheard. The name mentioned might have only been similar to Hathaway in pronunciation.
So he checked to make sure, and the Winter Assassin confirmed his previous answer.
The witch who turned him into a Wisp was really called Hathaway.
She claimed to be an Anzed and that she was carrying out a very important task, one that was related to the Anzed Witches and their revival. Because it involved the ownership of Cold Light's Grasps, the Winter Assassin unyieldingly refused her request.
So it ended in a battle.
Tragedy struck, and even the Winter Assassin, who was able to ambush Gods, was defeated under the assault of a series of strange Witchcrafts.
