"I think they're preparing to fire," Stormguard said after a moment. Luna moved to stand beside him to see what he could. As he said, the tanks were in position and seemed to be ready to fire. As they were watching, one of the tanks launched its payload across the river, although it would fall far short of the defences. Instead it landed on the riverbank and exploded. Two more explosions set off, the first one having set off a couple of the landmines they'd laid.
