Beside Artemis on that edge, a dozen worker-ponies were putting together bleachers. And just beyond them, there was a one-storey brick building partially built into the berm, with another couple of worker-ponies assembling some kind of wooden tower atop it. Beyond one of the berms, she could see puffs of white smoke rising in the air, and there was the occasional crack of cannon fire. On the opposite berm, Artemis could just make out the red-shingled roofs of the barracks buildings, each of which curiously has its own enormous, Equestrian flag billowing high on a pole.
