Long ago, when humans were still the weakest among all races. They asked God for mercy to help them survive from powerful werewolves, terrifying vampires, or cruel monsters and giants.
God heard their prayers and gave them a power called LUMINOS, taken from the word luminous, which means light. That power rested on a few lucky humans. With the help of LUMINOS, they became great wizards who helped humans survive amid other races that were so fierce.
LUMINOS owners could live forever as long as light hits their bodies. So, as long as the sun was still shining brightly, they would always gain strength. Some people who received the gift began to be greedy and oppressed other humans. Humans were screaming again to pray to God. Finally, God gave a punishment. They used their power to harm humans, then LUMINOS would disappear, and they would wither and die.
