Charlotte nods her agreement with Ellie, and heads off into the indicated direction.
"Here's the plan," She says as she goes. "It sounds like they're quite a bit bigger than us, and they outnumber us. If we spread out and flank them, we might have a better chance."
She then looks pointedly at Sildarin, nearing him and speaking low enough so that only he can hear her. "...I don't know what you're capable of, Sildarin. If you have any sort of spells that will help us take out those things that you saw, though, please use them to the best of your ability. Hang back and use your spells."
She then resumes her volume so that the rest can hear. "Those with ranged weapons, use them once, then close on them with melee weaponry. If you have only ranged weapons, then hang back and use them - but only shoot those not engaged with others, we don't want to be shooting each other and weakening ourselves."
I hope that I know what I'm doing. We only have one shot at this. If we screw up, then we end up like the other students.
But it won't end up like that. We'll take them down, and free our fellow students. Arm them with what we can, then free the rest.
Charlotte nods to herself, for no apparent reason. She continues walking to their destination.
