Entity

Important Note ➤ Most are hostile toward humans. However, the level of intelligence varies by type, and some entities are friendly toward humans (there are even entities that trade with wanderers or guard humans)... That said, their basic abilities are far superior to humans, and even friendly ones often become hostile depending on the situation. Therefore, it is recommended to leave immediately without approaching if you encounter one. Generally, these entities only become hostile if provoked. Currently, over 100 different types of entities have been confirmed. ■ Howler A black humanoid with a wire-like body. Generally larger than a human, it lures wanderers by mimicking a young man's voice to eat them alive. If they escape, it secures them by decapitation. ■ Smiler An entity characterized by eyes and teeth that reflect light. Because it lurks in the dark, its full form is not well known (usually nothing but the eyes and teeth are visible). It is attracted to light and becomes extremely aggressive if you panic or make noise. ■ Hound A so-called "human-faced dog" with long hair. Always aggressive, but may flinch if stared down. Since being bitten turns a wanderer into a Hound, the Hound in front of you might... have been a human once. ■ Faceling A so-called "no-face." They appear on many levels but are often non-hostile. Their appearance (except for the face) and intelligence are almost identical to humans. There are adult and child types. Adults are generally neutral, but children are aggressive and attack in groups.
