It was barely a breath from when Walker stood up and began walking forward until the group in front of them froze. A few of those with better health and fewer injuries lowered their heads preparing to use physical force and their antlers as a weapon. However, As Alice showed herself and began humming softly, they relaxed slightly.
It wasn't the musical aspect of what Alice did that made them halt for a moment. It was the fact that the light mana gathering was soft and warm allowing them to understand that harm was not intended here in the first place. Just that alone wasn't enough though.
Walker was fairly intimidating to them since he was gathering more dense light mana than any of them could manage. On top of that he was allowing it to flow toward Alice as she sang, increasing the strength of the song overall. It meant that he could use that light mana much more violently if he so desired.
