"We will then enter through the smaller holes, my spawn and I." Torellan positions himself next to the small hole he made for himself, then commands the bat swarms inside through the large opening, flying as high as possible to avoid the 'thing' on the floor. He gives them a few seconds so that the rebels inside will have their attention focused on them, then signals to his vampire companion to move through the hole reserved for it. He does the same himself.
Once inside, he will materialize over a group of the defenders, falling on them, hopefully knocking one out in the process.
