So what happened with the university is that Erichen Eizar Lessnerai was in fact fucking around with explosives, but not in a context of trying to blow up anything that shouldn't be blown up; a neighbor had asked for help dealing with a particularly recalcitrant tree stump and he had figured a small shaped charge would be effective. Someone walked in on him and explosives and freaked out and went and got someone else who also freaked out. Eventually a whole bunch of people were there, freaking out, and Sarlassa was there trying to calm people down and Erichen was not being especially conciliatory because he wasn't doing anything wrong and they were being ridiculous, and then one of the freaking out people knocked something over and Erichen was the only person who realized exactly how bad that was in time. He tackled his wife to the floor, trying to act as a human shield for her. It didn't do enough good.
