Goliath's eyes started to shine as bright as Anne a few seconds ago, surrounded by light mixed with darkness that weakened his light. Yet, it shined so brightly, didn't take long for him to acquire a spherical shape of light like a sun, burning everything in the proximity. Even Gremory had to step back.
For a few seconds, there was no darkness in Goliath anymore, and there he was, a creature of light shining and burning like the sun. Gremory stop seeing the connection between them at that moment. Goliath was free to do whatever he wanted at that moment.
Gremory prepared to deal with a traitor but then notice that Goliath was still following the orders, ready to kill Anne, who was speechless seeing the Abyss Creature with more affinity to light than her, who dedicated her entire life studying the light element.
