Sheeana was firing over the top of the sandworm, unsteadily and innacurately (these weapons had a kick to them that a lasgun didn't have and what she wouldn't give for a holtzman shield right now...) but it made the psuedo-Germans think twice about advancing. Still, even with the Worm, they couldn't hold this position forever. The Worm bellowed when Katara got close, stung by the water and she had to take a moment to shush it.

"Tauf! Are there any underground passages below us?!" She called to the earthbender.
