Carved Crystal

The fallen angel holds a lot of shadows. Much more than Gremory has right now.

The difference became clear once Gremory started to manipulate the energy. Converting his shadows into the big dark crystal was as hard as manipulating Qi. 

Just an impossible task, but he had to try it.

The dark crystal was becoming darker than before, compressing the energy and even changing the crystal size. 

However, that distortion was transforming the big dark crystal into something smaller with much more energy. Shadows kept spilling out of it since the power of Goliath was so great.

Still, the crystal was fully charged, and Gremory was not counting the energy absorbed by Goliath. With that extra energy, the crystal started to become unstable, and cracks began to appear. 

'Shit, can't break right now.'

Goliath didn't have any control of the situation anymore. Once Gremory started, he had to go till the end.
