"This is it," Leon said, his eyes locked on the shimmering crystal suspended above the lake. "The first-level dungeon's core."

Before anyone could respond, the tranquil surface of the lake began to ripple violently. Waves churned, and a monstrous figure rose from the depths—a terrifying amalgamation of shadow and water. Its massive form was constantly shifting, as if its body couldn't decide on a single shape. Writhing tendrils of liquid and dark energy surrounded it, coiling like serpents ready to strike. Its eyes blazed with an unnatural, piercing light, radiating malice and primal fury.

The creature let out a guttural roar, the sound reverberating through the cavern and shaking the ground beneath their feet. The air grew heavy with an oppressive aura, and the group instinctively stepped back.
