"Light Domain, Transformer Domain, Time Fragment Domain" 

The first senior had a domain with a theme closely related to the light element. 

Maybe this person's most dominant power was light element ability, but this was not a healing power. 

The light element ability either had a soft power to heal, create, purify, and boost, or had a strong attack power comparable to missiles, bullets, and even bombs. 

This senior had an aggressive light element ability as the core of the domain, and so, the entire domain was like a small sun full of blinding white light with some degree of heat that would be unbearable to many people. 

The aggressive light element ability was the best against the dark element ability, and Axelle's domain core belonged to the dark element. 

The light element domain was not as exquisite as Axelle's abyss-like domain, but this light element domain had a complete law of space and time, including the law of light element.
