How can I make this work.

Gurkirat, listening to the conversations going on around, and mostly above, him took a moment to contribute his thoughts. "I like this fire idea," he said, "but I'm not sure how we can be certain of our success until we go down later and find the corpses. And as Grumbleshanks mentioned, the moment there's fire we'll have rats boiling out of every exit we know of, as well as many secret access points that we have no way of guarding"

He paused to let everyone in the room consider his words and to discreetly take a swig from the water at his belt. Why was he so nervous? This is the beginning of what could be a grand adventure. "However, suppose we take note of the rats most frequently used tunnels and corner them in smaller chunks, and then either burn them with oil or detonate a bomb nearby. Wererats have keen noses and ears so we need to be careful of how much noise and stench we generate in our purges. If you allow me to refine the oil I can make a very clean burning fuel that will be suspicious, but not enough to arouse the attention of the whole wererat horde. "

Again Gurkarat had to pause and drink from his waist. He had no idea if any of this would work, and he was a lowly bard who spent way too much time in school! He had no experience in these things! "However, eventually we will be forced to attack the main nest, and for that I suggest we sneak in as discreetly as possible and plant some bombs to detonate the entire block and collapse it upon the rats heads. We'll need to evacuate the area above ground, but I think it will be worth it. What do you think?"
