"So you're saying that there were two witches" Tyson asked.
"No there were three. A third energy surge was also found after the extensive study, it was very weak but it was still there. I want the source of that third energy surge" Vanessa said making Tyson understand what Vanessa was looking for.
"You want that witch" Tyson asked for confirmation.
"That witch used the magic to create fire" Vanessa said. A spark can be created easily to light the lamp but to make a house or a whole town on fames need quite immense amount of power. It is not a very usual practice and hence a rare event.
