First Floor, Glacirith [1]

As I stepped through the Iron Blood Door and passed the Gate, I entered a passage shrouded in absolute darkness that stripped away all five senses.

I couldn't see my own shadow or the figures of my companions. I couldn't even hear my own heartbeat. The void pressed in from all sides.

Then, like a lone star in the endless dark, a single point of light appeared. It expanded, forming clear, readable characters before my eyes.

It felt just like seeing a system message.

[Welcome to the Tower of Chaos, known as the Dragon's Labyrinth, Aspirant.]

[The Dragon's Labyrinth is a 'Unique World' created by a Fallen God.]

[By the authority of the 'Creator,' three rules have been set within this world.]

[Breaking any of these rules will unleash the calamities sealed within the Shadow World (Floor) of the Tower.]

[The three rules of the Tower are listed as follows:]

[Rule 1: It is forbidden to leave the tower without completing the trials.]
