The group proceeded with cautious stealth, spending no small amount of effort before they finally reached the foot of Shaded Cliff.

It was a steep cliff face that never saw sunlight year-round, its rock walls covered in slick moss and shade-loving plants.

At the bottom of the cliff lay a small pool. Its water was pitch-black, radiating bone-piercing cold.

He signaled for his team members to keep watch over the surroundings while he silently approached the pool.
