The Immortal Ones, the Void (Hollow Night. They cannot be defeated by normal means.) are invisible creatures who wander around the
Voids are dark shadows that are incapable of thinking and only move on their instincts to consume Existence. One can become a Void by overusing EXS abilities or gathering huge amount of EXS within one's body.
Normal people aren't able to perceive or interfere with them. Only the most powerful Voids can materialize themselves. Voids also become visible when they get close to high concentrations of EXS, such as the Abyss.
When a person is bitten by a Void, they become able to perceive Voids for the first time. This is also what triggers a person's awakening as an In-Birth. But if the person isn't able to keep their sanity when they witness a Void for the first time, they'll turn into a Void.
Voids cannot interfere with the real world. They only attack the people within the realm of Hollow Night. Once the Night ends, the Voids remain in the alternative realm and wait for the next Night.
