He knew the spells were about to be sent towards him as he had ordered by the feeling of the elemental mana in the air.
Midnight came out of his shadow and unleashed a wicked roar causing the entire area to become chaotic with different elemental mana. Her draconic aura seeped in to the training space near her causing almost all the spells to fail or dissipate. She had been watching Onyx the entire time and came just in time to avoid her little brother being harmed.
Creation is hard, cheer me up!
