The most unique and mysterious inhabitant of the Lost River was known as a "Warper", named for its ability to rip open the fabric of reality and create a doorway to another location in space, which could "warp" matter that passed through it to the other side of the "portal" instantly, mainly the Warper itself. However, before the portals closed, other creatures could pass through them just as Warpers could. This was used for many things, from catching prey to escaping predators, or just warping to join other Warpers to socialize or congregate to form migratory flocks.
Warpers could also shoot a ball of green teleportation energy at their enemies that were too fast for the Warper to teleport away from, which teleported the target about 100 feet in the direction the ball was travelling upon impact. For more persistent enemies, the Warper could charge up a larger blue ball of energy thatteleported targets 3 times further than the green ball, but essentially worked the same way the green one did; it encapsulated the target in teleportation energies as the ball moved forward, and once the target was fully enveloped in energy, it warped them in the direction that the energy was travelling until the energy dissipated and it spat the target out violently, disorienting it while tearing at its body as it threatened to overload the target body's atoms with temporal energies. The Warper's portals didn't work the same way, instead steadily spreading out its temporal energies evenly throughout the teleporting being's atoms, making sure not to overload them and safely transporting all of them through space to the other location.
The Warper was a unique creature indeed, and its appearance reflected that perfectly. It had a crab-like mouth and an odd, frilled carapace for a head,and its entire body was dark shades of purple and violet, and it had 2 spindly, crab-like arms that ended in points, each one being lined with miniature temporal energy-producing organs to allow the Warperto blast the orbs of temporal energy from its forceps-like arms. Its arms and face almost made it resemble a praying mantis, but the rest of its body made it much different-looking.
Its body resembled a long, flowing cloak that ended in two tentacle-like flaps in the back, that complimented the Warper's three, long tentacles coming from the bottom of its abdomen. The front of its midsection was see-through and had a bluish-purple tint to it, and inside the Warper's body were visible organs, such as a heart, complete with thick, oddly-colored arteries, a stomach, and some other organs, one of which glowed a soft green color right before the Warper opened a portal or shot a green warping orb, and it turned to a soft blue when it was about to shoot a blue warping orb, or, in rare instances when Warpers needed to jump entire biomes at a time, when it created a portal with a blue border of temporal energy holding the doorway open. The Warper only did this when its usual portal and both of its energy orbs failed to deter or help it escape from predators, but when Warpers used their blue portal, it sent them a little over half a mile away, or about one kilometer in metric. Warpers could only do this once, sometimes twice, before having to recuperate from the strain using vast amounts of temporal energy at once placed on their body.
Warpers almost never used this ability, the only times I ever saw it being used in natural situations being when they ventured into Reaper territory and all other measures failed, and, even more rarely, when a Warper needed to escape from a large group of predators, such as a swarm of piranha-like Biter Fish or a family of angry Bonesharks. Both were fast enough to eventually catch the less agile Warper unless it warped out of their line of sight and the range of the rest of their senses. Due to their ability to escape from all forms of danger, Warpers rarely fell prey to any type of predator, but when it came to their diet, almost anything they could get their mandibles on was fair game. They used their abilities to catch a variety of fish, such as Hoopfish, Hoverfish, Peepers, Boomerangs, Reginalds, Holefish, Garryfish, Oculus, Eyeyes, even Airsacks if they were feeling desperate enough to settle for the mostly flesh-less body of an Airsack, and, if they were feeling brave or were sufficiently stupid, they even preyed on lone Biter Fish, often not getting to finish their meal due to the fallen Biter's friends usually being nearby to interrupt the consumption of their friend's body.
Warpers were ruthless when it came to pretty much everything, and were intelligent enough to realize that due to their abilities, they could actually afford to be as ruthless as they wanted without consequence. However, when I came by, they left me the hell alone, knowing the hard way that when shot at, I could shoot back with a dangerous projectile of my own: a vortex torpedo. Warpers got a taste of their own medicine with the vortex formed from on eof my torpedoes, being sucked in and flung into the open ocean at high speeds, having no say in the matter and being too disoriented to warp themselves out of the vortex's range of suction.
They didn't mess with the Cyclops either, knowing that the torpedo-launching Explorer was waiting inside to deploy and fire back should the Mayflower come under attack. Little did I know that the Warpers were more intelligent than any other creature native to Subnautica, and held the key to the answers to the questions I so desperately craved to have the answers to.
