Utterly Mad

The town you were staying in was a three leveled fortress of a town defended by the town militia. The inn the three of you were staying in was on the top tier which was only accessible by a crane operated elevator. The other two 'tiers' were just different levels of the hill that had been leveled for building on. The three of you had heard some talk of the Vultures during your stay, mostly that they had tried and failed on a few occasions to attack the place.
The three of you had woken up and  were going about your morning routines when you heard the town's siren go off. You hear something crash into one of the buildings near the inn you were staying at and screaming. The three of you leave the building and are greeted by the sight of the town militia leader shouting "We got Vultures attacking! Get to the walls and take them out."
