Deep in the dark below the surface of the water, you have found yourself lost amongst the darkness. It's only you were alone, or maybe you wish you weren't.

Welcome to the decaying ruins, part of my Back Rooms series. Exactly how or why you've ended up here is irrelevant. There's no way out, and it only makes you put more water and darkness. There are no shallows here; there is no surface to be found. The closest thing you get is the ruins, which can occasionally have occasional air pockets waiting for you.

⚠️ blood gore monsters, and evil things, etc.

The decaying ruins are the name of the place, but it is also a single biome out of several that exist; the ruins are simply the most common. The king ruin is a massive sprawling endless Labyrinth of buildings in varying states of decay, some look brand new as if they had just been constructed, others as if they had been down there for centuries. The ruins are most common as well as the most active, but luckily, the safest area. Most of the much larger and far more dangerous creatures are not commonly found in the ruin. The next most common buying area is the void. This is the most difficult to leave; it is an endless dark ocean. The void is extremely easy to get disoriented in; it is near impossible to know which way is up, down, left, right, or even which way you've come from. Everything is just darkness, and the occasional lights that are seen are very rarely good. The upside to winding up in the void is that if you are hunting creatures, there are many of them here, although they may be difficult to locate. On top of that, if you are looking for destroyed vessels, doorways, or debris, it is very common here. Next are the caves' endless caverns and twisted stone passageways. The caves are easy to get lost in, difficult to navigate, and very, very difficult to leave. It is extremely easy to get boxed in or trapped within the caves. The lying shallows are similar to the void, but the water is much lighter. However, no matter how high you swim, no matter how far you go, you will not reach the surface. There is no surface here; the true origin of the light is unknown. You'll never be able to find it. The shallows are a rare occurrence; however, they are mostly safe, as larger creatures rarely are found here, and even then, they are very easy to avoid and very easy to spot due to the lighter water. There are many, many other biomes, although they vary drastically; these are the most common.

(Monsters)

The Phantoms' danger is moderate to low. The Phantoms most commonly found amongst the reefs and the ruins. They can vary drastically in shape, size, and even intent. Believed to be the Lost Souls of those who ended up trapped within this place, the Phantoms, for the most part, stick to themselves, most rarely even noticing the world around them as they wander endlessly. Although uncommon, some Phantoms are known to become agitated or aggressive, especially if someone or something interrupts their movements. Rule of thumb: Be cautious and ignore the Phantoms.

The glistening lights, danger low to high. most commonly found in the void and the false shallows. The glistening lights are a series of strange, brightly colored glowing orbs and balls of light. They can be found almost anywhere, but are most commonly found in the void and false shallows. Exactly what they are is uncertain, but the glistening lights on their own are completely harmless, simply balls of light that appear and disappear throughout the water. However, despite being harmless, some do hide dangerous secrets. Several creatures have luminescent markings or features that resemble the glistening light. Others will use glistening lights to hunt prey, essentially using the lights as a distraction to sneak up on unaware creatures and travelers. Rule of thumb, the lights are better avoided; they might not be what they seem.

The Titans' shadow is low to moderate. The Titans' Shadow is most commonly found in the reef shallows and ruins. This is a phantom of a time; even this twisted place has long forgotten. The Titans' Shadow is a phantom or ghost of sorts. It appears and disappears randomly, taking on a wide array of forms, although in most cases, it does have a vaguely humanoid appearance. Regardless of physical appearance, it is massive. These shadowy Giants are completely peaceful; however, they do cause I'm intended or at least not knowingly intended. The shadows themselves seem to be stuck in a Time long erased. Their movements can cause waves and destruction to objects or beings they come in contact with. They do not hunt or mean harm, but they cause it simply due to their sheer size. Rule of thumb: keep your distance.

The behemoth is of medium to great danger. A mix of monster and what may have once been human, the behemoth is a twisted amalgamation, its shape very drastically but resembling some sort of cross between human and sea creature. On average, they are 10 ft High and tend to be quite muscular and surprisingly quick in the water, appearing most commonly in the Reef, void, and caves. How dangerous a behemoth is drastically on how close you get and how hungry they are. They are extremely territorial creatures, claiming areas as their own and lashing out at everything I get to close. They're all solely carnivorous. Rule of thumb: avoid or distract with meats, they will go to something that they smell first, rather than something in a suit.

The electric Kraken Danger non-existent to extreme. Most commonly found in the void or sunken Zone. hiding in the darkness, but with luminescent patterns, the electric Krakens claim massive territories surrounding ships or shuttles of all kinds, from sunken vessels to things that seem frozen in the water. Should someone or something enter their territory how dangerous they are varies drastically based on the individual, how close you are to the territory, what your intention is, and whether or not you have tampered with what they consider theirs. They may ignore you, they may hunt you down, they may simply watch you waiting, or they may even claim you. It all depends on the Kraken.

If anyone would like, I could attempt to add a survival mechanism, essentially oxygen levels, hunger, etc. As of now, I'm not going to, but if someone would like me to, I am more than happy to add it. I was debating about it, but I've decided I'm not going to at this moment.
