He got the necessary pieces done yesterday; today was merely having Sapphire, in dragon form, shift them about slightly once he put the cap on top of the now loaded 'bombs.' That took a couple hours, not really hard, just mentally exhausting because he checked everything twice, before sealing the keg in its boulder. That done, he looked about, and reached up and rubbed Sapphire's chin, idly contemplating the field. "Much as I would love to thin the trolls down some before the bombs, I am not going to risk it. That forward group's survivors have to have met up with the main group by now, and they know someone with power is here. Too dangerous, and don't want to put them on edge before the fight."<br/><br/>He glanced upwards, as a scrying spell washed over the area, and frowned to himself as it vanished just as quickly. It was the first one he had sensed, though it was possible he had missed some during the working. Simply turned and went back toward his wall foundation, and sat down, humming to himself. He shook his head after a moment, his eyes drawn to Sapphire's form again as she walked toward him. "I can't think of anything else to do at the moment. Got the charges set to go off closest to the wall first, and the second line is in the middle. That way, the burn teams don't have as far to run if the trolls want to sally forth to try and defend their regenerating buddies. Which I doubt, but it doesn't hurt to be prepared.<br/><br/>Can you think of anything to do before the human army gets here?"
