When Oak and Vesa returned they were amongst themselves about something. Lukas only happened to catch the tail end of it, but it didn't seem to be about anything important. He heard a couple of things about Vesa's teaching. Grappling, general weak points, advice, etc. There was also some discussion about the general going on, such as the lack of sound.
Vesa instructed the two of them to warm up, much like they did yesterday. After about twenty minutes, a sound did echo out. It wasn't close, although it did originate from Mystic Camp itself, yet it was ear-piercing. Lukas dropped his tachi and both Oak and him covered their ears.
The sound was a loud screeching whistle, whoever blew it did so with so much force the sound itself cracked and went even higher in pitch. It was three long, distinct notes, followed by five short notes in quick succession.
