The Secret Room: 099

Beneath the First Training Hall, hidden behind an inconspicuous wall, lay a staircase leading to Room 099. The air was stale, heavy with an eerie stillness.

Who built this staircase? Was it a collaboration between the Swordmaster and Magician clubs? Or had it always existed, shrouded in secrecy? Regardless, here we were, standing before the door rumored to house the "Treasure of Letters."

After a week of speculation, anticipation ran high among us. Excitement mingled with a hint of unease as we prepared to uncover what lay ahead.

The unique key trembled in Rindo's hand as he glanced around, seeking silent confirmation from the group. Steeling himself, he slid the key into the lock. The door, indistinguishable from any ordinary training room's, creaked open with a faint resistance.

"Whoa, this place is massive!" Rindo exclaimed, craning his neck to take in the towering ceiling.
