Blinding Depth are dark underground biomes generating in the abyss.

This caves are dark places with no crystals. A lot of sculk cover its walls, as well as corrupted abyssalite, a stone too deeply corrupted to be used for anything. Living Sprout are generated in those caves which makes them very dangerous to explore without any Stealth armor equiped.

Ancient Citadels can be generated in those caves.

Nothing spawn in the this cave, except for Parasytes from Living Sprout and Warden from shriekers.
