Cassandra entered the Training Room and picked up a bow and some arrows. She had been practicing archery, and she was becoming better at it. It was probably the only thing she was good at, besides making the soil rise and accidentally bump into trees and, occasionally, other campers.
She nocked an arrow, aimed for the middle of the target, and let go of the string. The arrow tip dug deep into the middle of the target. Cassandra nocked another and let go of the string. It landed right beside the first.
She put on the sheath of arrows and grabbed a single arrow. She started walking and aimed for the next target. As she let go of the string, it landed right on the center of the target, and she nocked another arrow and continued walking. Cassandra let go of the string. Dead center on the target.
Continuing the process, she vaguely heared the door to the Training Room open, but she didn't turn to see who it was.
