Light Bringers

Light. The conqueror of darkness. So imposing that darkness hides behind objects in its presence. So imposing that darkness only roams when light slumbers.
No matter how bright the light, the darkness, however cowardly, will always exist. Being consequently stronger to deintensify the light's power. As life flourishes, it imitates that of what it's made of. Most show their light, while they bury the darkness within themselves in the presence of others' light. Equally, they expose their darkness in the presence of such.
Cultivating inside those who can't stand to mask their inner darkness any longer, they lash out, forcing their shadows on the light of others. Despair, anguish, fear, every cold emotion in them lashes outward.
Only those who shine the brightest light upon the darkness can vanquish these adverse emotions, subsiding their thirst to plunge deeper into darkness.
