Alelip thinks on Marin's report for a few moments, and says, "Thank you, Marin. At least we will not run short of weapons or fire when the gnolls come calling again. When we finish our shift, come with me and I'll have you draw a map of what you saw."
He pauses for a second, then adds, "We'll leave the second hidden passage for tomorrow. I'll accompany you down with a couple of others and we'll figure it out. Until then, back to your post."
