Dark Fantasy.

The Lake of Black Blood, known as the Heart of Y'lgaroth, is a dark, viscous body of water that bubbles ominously. Its shores are lined with grotesque, organ-like formations, hinting at the twisted life that thrives in the surrounding Gardens. An ancient elven demon lurks beneath the surface, making the area perilous for any who dare to approach too closely.

The lake's surface is a deep, inky black, with occasional bursts of dark red bubbles that rise and pop, releasing a foul odor. The surrounding landscape is eerily quiet, save for the unsettling sounds of the bubbling water and the occasional rustle of unseen creatures.
