As if in answer to your words, the circling group comes around from the front of the church and passes those gathered at the back. "Here, what's taking you laggards so long to burn through this door?" barks a melodious female voice, probably an elf from the sound of it (though her language use is hardly typical of any elf you've met). A particularly weaselly-looking kobold squeaks in response, "Wood not will burning for good! Us keep break our fire-sticks before theys can get through." "IDIOTS! TRY THIS!" shouts a second member of the procession, and he pulls out an incendiary-like device (Mornok recognizes the technology as Dwarven immediately, and in fact the speaker could easily be a dwarf from the shape of him, though atypically tall for the race). Tossing the spike-shaped object toward the unseen rear of the building, he is rewarded with a big "boom" and a huge gout of thick black smoke, which quickly spreads and blankets the entire area in a gray haze. The bomber laughs and yanks on the choke-chain to urge his drake forward; the kobold members of the mobile group twirl and leap and jabber in excitement at the detonation, while those who were around the door can be glimpsed cringing and covering their heads just before it explodes, and then scramble to recover their tools before they are fully obscured from view. The patrol then moves on again, vanishing into the cloud and presumably continuing on with their route. Assuming they keep their previous movement rate, they will likely take about five full combat rounds to make it back here, giving you a fair amount of time to use the smoke as cover and sneak up on the door guards.
