"Fire salts are gathered from the remains of flame atronachs." Meesei explained. "They have several uses in alchemy, among them are concoctions that, when exposed to enough heat or energy, will explode like a fireball. Sabine and Ariel should be able to attach fuses to flasks of the substance. They can plant them in the storage tower, light them, then move on to the production tower. They will only have so much time to reach the other tower, but even if they detonate before they are ready, the delay should help. The rest of us will make our escape once you detonate the second tower, so I would advise you to attempt to find the witch responsible for producing the gas before destroying the production equipment. Hopefully, she will go to the tower as you suspect, Ariel." Meesei's expression turned a bit more grim as she moved on to her next point. "As for the hagravens, though, there is something about this I hope you understand. With the rest of the witches, it is possible we may have to kill them, but more than likely, we should be able to incapacitate them by other means, especially if I can disrupt their sentinels. The hagravens, though, they are another matter. From what I have heard of those creatures, and what you describe, they are very dangerous beings. Even with the reflection potion, they are crafty. I will try to be non-lethal, but there is a [i]very[/i] strong possibility that will not be an option. Out of any of the residents of the keep, they are the ones who will be most likely to force us to kill them. I just want to make sure you understand that." Meesei said with a serious expression, her eyes locked on Ariel.
