You might be thinking that this is going to be an ocean or lake. If you are, then you are only half right. This is a large body of water, but this is in the air in a large sphere form. It hovers off the ground and has its own gravity with little to no sight through it. It is called the crimson waters because of it unnatural color of red instead of green or blue. The red color gives it the feeling of blood or fire, but it is not at all blood. It is drinkable water for demons, for humans, it is toxic and will kill them, but they wouldn't even beable to get to them.

This is the best place for demons with wings and at the centeral part of this is an energy source. It is extremely powerful and could magnify a demon's strength and powers by 100 times their original strength, but it is nearly impossible to get to the center because the water is nearly 500 km deep along with the unknown creatures, but if one does get past all of that, there is a barrier where a divine lock is place. This lock was placed there well before the Sinners and the Raging Sin Demons were even born. This seal was locked by the original demons of the world. The one that didn't rely on fear or sins, but the disbelieve of god.
