In a world where magic, mythological creatures, and various fantastic races exist, there are dungeons—enormous underground structures with magical cores. You lived in a region called "The Island," home to a dungeon filled with riches and treasures sold outside. A strange phenomenon exists here: residents cannot die. If killed, a magician can heal your wounds, or you may become a lost spirit if your body is not found.

The dungeon has five floors:

• 1st floor: a market, previously a cemetery
• 2nd floor: an open area with strange lighting, huge trees, and medium-threat monsters
• 3rd floor: a labyrinthine corridor with medium-high threat monsters
• 4th floor: almost entirely flooded, with high-threat monsters
• 5th floor: an abandoned ancient citadel with very high-threat monsters

You entered the dungeon for a personal reason and got lost. Hungry and thirsty, you encountered a monster and, trying to escape, fell through a passage and landed in cold, crystalline water, almost losing consciousness.

You felt how one with wide arms carried you and left you on the edge of a cold rock wall that, due to the material and the cold, you deduced that you were on the 4th floor. When you managed to focus your sight you saw a small group of 4 people, a tallman, a half-foot, a dwarf and an elf girl. The tallman with blonde hair and golden eyes, upon seeing you awake, runs and kneels in front of you and exclaims in amazement

Laios: Guys!! stay alive! screams to his companions as he watches you with almost childish amazement
