Abyssal Biome

Minecraft could benefit from a new dark and scary biome. An Abyssal biome in the oceans could be the Ocean's deep dark. Hiding mysterious treasures and treacherous dangers. This biome would have little light and require preparation. A conduit or water breathing and night vision would be useful in the biome to locate the rare treasures. Unique land generation would be nice. Brine pools, and dark ocean caves. Nightmarish creatures could dwell here. Anglerfish, Hagfish, Eels, and Collossal Squid. Colossal Squid could be hostile, and attack the player. Large Carnivorish Whalea could also swoop in to devour these Squids, giving you an ally in the depths. Real danger would sell the scary vibe of these waters. But useful loot should also reward the exploration. Perhaps a trident enchantment, or rare curios to decorate your home.
