Balas growled in frustration as her reason failed to reach Halite, she let her Ax free as the massive gem resumed his rampage and dived to the side, making rather sure she was between Halite and the other,  and most importantly the Massive red-crystal heart of the sanctuary. As she did the vibration from Balas's hand seemed to rapidly shiver up her arm and into her throat. When Balas ruby opened her mouth seconds later, she didn't yell, cry, or scream. She roared. It was a deep rumbling sound that was more akin to the cacophony of an avalanche than any sort of noise to come from a living creature.  The sound leaving her mouth was visible cone of force, shimmering in the air and tinted a faint reddish color.  This was not her most focused sonic attack, but she wasn't truly attacking now, she was defending. the cone contacted the oncoming hail of gems and the faltered like a swimmer against the current of a powerful river. Soon the lost all momentum, and Balas sensed her bellowing.  The kunai clatered to the ground and the bubbled Gems drifted in their new places. 

"If you truly believe that is a fair trade, without even stepping outside to see where this base is located, then you never cared about this world, or any of the life on it." Balas said in a deeply cold voice, far different from the commanding if reasonable tone she was using before "Halite, you are a hypocrite and a traitor to your own beliefs. There is no gem in this room more dangerous and worthy destruction than you. I give you one final chance. If you will not work with us, take this new life you were given out of kindness and hope of another who wants to save this world, and leave." This time both her hands shimmered with the vibrations of her gathering power, and there was a similar shimmering glow about her throat, and the bone deep rumble that emanated from her body this time could be felt in the ground, the discarded weapons on the floor rattling with its vibrations.  She spoke again, her voice coming out with an odd wavering quality. "Don't think I'll simply defend again, Halite, forgiveness is not truly in my nature."
