The Bloop

The Bloop is one of a small number of truly gigantic creatures that reside near the bottom of the world's oceans. The exact size of each creatures is unknown, but so far the smallest one found is no less than several kilometres in length. Often described as a cross between a fish and a lizard, they practically never move for years or decades at a time.
The Bloop are so named because once every now and then they erupt with a loud noise that travels for miles underwater. Normally, these Bloops aren't that powerful, but every few years they let loose with a wave of sound-energy that carries from one end of an ocean to the other.
The secular world has not discovered the Bloop because they reside so deep within the ocean's waters and they never move. Also, years of coral growth and incrustation have caused the Bloop's bodies to resemble the surrounding ocean floor, making them blend in near perfectly.
The New World Order and other powerful Chapters are aware of the Bloop as well and so far have made no move against them. Some factions within the organization have caused for 'destructive testing" to see what a Bloop is capable of or how one can be damaged, but so far other Adepts (ala the Scions) have managed to talk them down (one way or another...).
