As Reign turned the vault wheel slowly, it generated a loud creak. Judging from the sound, he could tell it was old and rusty.
The wheel had rusted so much that it became extremely heavy, well beyond what an average person could turn. This neglect suggested a lack of maintenance for along time, making it stiff .
CREAK!
CREAK!
The sound of the vault door's gears turning reverberated through the space behind it, akin to the interior of a cave.
CLICK!
After finally unlocking the vault door, he grasped the handle firmly. With a steady pull, he gradually swung it open wider until it was fully open, revealing another corridor .
The scent of death immediately filled his nostrils, and through his undead vision, he could see a black-red aura emanating from the inside.
It was condensed, a sight that would normally signal danger.
