There were three raider ponies inside, barricaded and waiting nervously for us to show ourselves. I waved Calamity back, then backed up myself. A moment later, I sent several of my new grenades down to see them.

“oh fuck!” came a voice from below, followed by three rapid explosions, then a silence marred only by the sound of falling debris.
Creeping back down, I found three bloody corpses and a hell of a mess. The rest of the building was raider-free, although Calamity and I had to clear a few tripwires and “disarm” a bouquet of grenades hanging over the front door before I was ready to declare the building safe for looting. (Sadly, neither Calamity nor I had the sort of finesse with explosives and traps that would allow us to safely collect the grenades. Disarming the grenade bouquet was done at a distance, and involved a thrown bucket and a lot of running.)
