As expected, the line of sentinels fell to them easily enough, attracting a real threat from within the keep's walls They were able to use trees for cover, but that would only take them so far. Meesei dashed from tree to tree to bring herself closer to the walls, using her wards to protect herself in between cover. Her goal was both to draw their attention away from her pack, and to get close enough to use her necklace on the skeleton archers. There were a few skeletons closer to the walls attempting to stop her advance, but she used her necklace to deal with them quickly. 

Meesei raised her ward as she began her final dash to close in on the wall. She was met with a wave of frost, but her ward held strong. At the same time, she retaliated with an explosive fireball which detonated on the wall just a few feet away from one of the witches. Her ward easily blocked the effects of the fireball as well, but fortunately, the explosive radius of the fireball was larger than they were expecting, and another nearby witch ended up with her robe igniting. She was not actually harmed, but she was distracted while she attempted to put out the blaze. Once behind the new tree, she grabbed a hold of her necklace and leaned out from behind cover to deal with the archers on the wall, using her wards to defend herself when needed. 

Through this advance, Meesei had drawn much of the spellfire to herself, but she would not be able to maintain her wards forever. Even as the archers fell one by one, the mages presented a threat that was not so easily eliminated. Even if they wanted to kill them, their position was too strong of the pack to gain any real advantage. They would need to transform and scale the walls soon enough, but Meesei intended for them to hold outside for as long as they could to give Ahnasha and Ariel as much time as possible. 

Inside, Ahnasha silently nodded as she took the fire salt mixtures and headed to the opposite side of the room. She placed them in spots that were not immediately visible to someone just passing through the room, though ideally, no one would enter the tower until the flasks had detonated. Since they were spreading them out across the base of the tower, the entire structure would come crumbling down once they detonated. Most, if not all of the gas stored there would be destroyed. With the final tower, there would be no issue with using fire runes and the unstable nature of the production facilities themselves to collapse it. They had just enough fire salt flasks that they could spare one to serve as the catalyst for that detonation. She placed each flask without yet lighting the fuse, instead waiting to make sure both of them were ready before igniting them. The fuses were long, but they would need to move quickly in order to get to the next tower before they detonated. It was entirely possible that the flasks would detonate before they could make it to their final target, but as long as they were most of the way there, then the delayed detonation would have served its purpose.
