"I don't see the girl, neither here nor there." says Thony, making a step back from the window to have space for his musket and takes an aim at the thing, but does not shoot. Sarina does not seem like doing much either.

Thony: step, ready a shot at the machine in case things go hot (e.g. anyone attacks anything, like Kallak vs machine), active perception (1d20+6)[21] (can we make any sense of what the thing is vocalizing?) forgot we have a thread for that
Sarina: delay until Thony has taken his shot (she sees him taking the aim), then step or move to have a line of effect (requires an open door or a broken window; a window that was just shot through will do) and place a grease under the machine
