Light is kindness.

Light is forgiveness.

These three words were brought to Azeroth by the holy light.

If it's more direct,

This light is Lu Na.

It's Alda.

This is something from central Saudi Arabia.

The power of light is the power of Lu Na.

For example, there are no paladins in BL.

Because BL doesn't trust Narunart.

Later, the blood elves kidnapped Muru, a leader of Naru.

Draw the power of the holy light from him, and BL will have a paladin.

Humans and Germans always say, May the light guide your way.

It means to let you go out with Naru
