"If I can have everyone's attention!", Aiden shouted, making the surrounding noise simmer to whispers. "These fights are friendly spars. It's expected that every challenger shows his or her skills without holding back while making sure that no serious injuries occur. However, accidents happen, and we expect everyone who gets in here to agree that regardless of what happens during the spar, grudges will not be carried outside. If you have the ability, show it during the fight. If you don't, you need to accept the outcome." He looked at Sean and Allen. "Understood?"
Sean and Allen both readily agreed. They are used to this.
