Finally done! Please note that while having spent their lives together, Aerys and Ryza have variations within their history sections.

Name: Aerys
Nicknames: Sunshine (rarely used)
Title: Innocent Knight
Age: Not sure, appears sixteen
Gender: Considered female
Species: Guardian -A race of humanoid robots created by the gods of their homeworld to protect and aid humans and human-like beings. At first glance they're almost indistinguishable from normal humans, and sport the ability to form personalities and feel emotions similarly to humans.
Personality: Aerys isn't exactly what you'd expect from one belonging to a race known as Guardians. She's almost eternally kind and cheerful, and is known to have ungodly patience...which she needs all three of to balance out her sister model, Ryza. Often, she displays a childish curiosity towards things she doesn't understand (which is a lot these days), and enjoys learning, especially about how mechanics work. A pacifist at heart, Aerys isn't typically quick to fight, nor does she think violence solves problems, and hates seeing people hurt, particularly through trying to protect her. She's also almost trusting to a fault, and will often accept even the wildest stories as truth if she has no reason to disbelieve them. She believes everyone has good in them, and that there is a way to draw that good out of anyone if you take the time to try...though she won't give you time if she sees you hurt someone for no reason. That's when the kind hearted pacifist gives way to pure protective programming that demands the threat that activated it be eliminated.
Appearance: Looking at Aerys, one wouldn't guess they were looking at a robot with advanced AI and strong directives geared towards protection of others. On the contrary, one look at her otherworldly blue eyes and warm smile might have one convinced she's the one in need of protection. Her eyes and charming smile are set in fair skin and framed by mid back length golden blonde hair, and her height of 5' 6" doesn't cut a very imposing figure, either. She's commonly seen wearing an almost childish looking and somewhat ornate pale blue sundress with white elbow length gloves as well as white shoes that look much more like knee socks than boots, like she claims they are. Believe it or not, her clothing is far more durable than it appears. More often than not, Eternity (her halberd) is "magically" attached to her back as well, making her look even more odd than she normally does. Occasionally, she can be persuaded into a pair of jeans and a t-shirt if she's doing mechanic work, but that's not even very often.
History:
Spoiler:
Aerys and Ryza were created on a world vastly different from Promethia as part of a race known as Guardians that were created by the gods...or, a bit more accurately, one god, with a little bit of cooperation from the others in obtaining materials. While not the first Gurdians ever created, they were the first "sister" models ever created. Unlike most Guardians, who often spent months searching for another who they felt they could trust to watch their backs in battle, Aerys and Ryza knew they were meant to be together from the very start, something that greatly pleased their creator not that they spent much time with the god before being sent out into the masses of their home world to start fulfilling their duty as Guardians. While operational for only a short time, the two gained quite the reputation for their team fighting skills among Guardian ranks, which may just have been their undoing.

The last thing about their homeworld Aerys remembers is being paid a visit by the god who created her race. He'd come while Ryza was out, and he gave her a very special mission, however she can no longer remember what that mission was. Whatever it may have been, she knows it must have been dangerous enough for her to become damaged enough to enter a forced shutdown for repairs. Everything after their creator's leaving is mix between perfect blankness and a snowstorm of colorful pixels accompanied by static. The next thing she remembers is waking up upon impact with the ground just outside of Shipwrech, and doing so without Ryza as well as not the slightest clue as to how she ended up there. Her best guess is a coordinate error when another of their kind or a human attempted to transfer her to a medical facility, but that's really just a guess.

Abilities:
Built to Protect-Being created with the sole purpose of protection in mind, Aerys is stronger, faster, and just all around better than your standard human being, however this is evened out by her inherent desire to protect people, as well as by a slightly off sense of balance, which can turn her into a bit of a clutz at times. She also sports an on board repair system that mends most of her injuries. Minor things like cuts and scrapes can take a few seconds to a few minutes, more extensive damage can take days, even weeks, and some require immediate shutdown on Aerys' part to take care of the damage.
Fountain of Knowledge-Aerys was created with a very large informational database inside her "head," and sensors that love to bombard her with questions and pull up useless prompts. Most of it since arriving in Promethia has become absolutely useless.
Networking: Another mostly useless ability, Aerys has the ability to connect to other nearby Guardians to communicate and share information. This ability is typically more used by Ryza to gain access to Aerys' working information databases.
Equipment: A halberd she calls Eternity. It's as long as she is tall, the blade itself bears a strange blue hue to the metal, and it's made of one of the toughest metals found on their home planet. She's had it as long as she can remember, and it stays attached to her back through a peculiar magnetic system when not in use.
Other:

Name: Ryza
Nicknames: NA
Title: Broken Protector
Age: Not sure, appears sixteen
Gender: Considered female
Species: Guardian
Personality: Unlike her sister model, Ryza is generally cold and unfriendly to anyone that isn't Aerys. She's known to be very blunt and rude most of the time, but she's still someone you want on your side, especially if you need help fighting--she and Aerys make an incredible team, and she knows and acknowledges this, even if Aerys won't. She often tries to hide her inherent desire to protect, and is plagued by a deep sense of guilt when looking at her sister model, though she's unsure why. She's also the victim of frequent head pain, though she's quick to deny there's anything wrong, and remains irritable when the pain decides to stick around. Careful, though, making her mad enough may cause her to lose control...and you don't want that to happen. You really, really don't want that to happen.
Appearance: At first glance, it may be a bit difficult to tell that Aerys and Ryza are related. Look a bit longer, and you might recognize the shape of their faces are similar behind Ryza's wall of inky black hair, which falls board straight to her mid back. She also bears the same otherworldly blue eyes Aerys does, and she seems to wear a soft smile by default that hides her prickly nature. Their faces are where the similarities end, though. Ryza stands about four inches taller than Aerys, and gives off the impression that she’s the “older” sister and Aerys is the “younger” sister when they are, in fact, twins, and you’d never catch her dead in a dress. Most often she can be seen in what appears to be a black, sleeveless leather turtleneck that zips up the front and has matching armwarmers to go with it alongside a well-worn pair of jeans that are mostly swallowed by a pair of black knee high lace up boots. Altogether, this combination often makes Ryza look far more pale than she is.

Aerys and Ryza were created on a world vastly different from Promethia as part of a race known as Guardians that were created by the gods...or, a bit more accurately, one god, with a little bit of cooperation from the others in obtaining materials.

While operational for only a short time, the two gained quite the reputation for their team fighting skills among Guardian ranks, which may just have been their undoing.

While Aerys never seemed to think much about their job as Guardians, Ryza paid it a bit more thought--she always had been the more serious one, however her thinking took things a bit...far, to say the least. Her wondering included the fact that humans occasionally hurt each other, both on accident, and for other petty reasons. Eventually, in trying to determine the best ways to protect humans and human-like races, Ryza eventually came to the conclusion that the best way to protect her charges was to end them to a place where none of them would get hurt. The best way to protect them was for them to pass on...to die. Coming to this conclusion essentially broke her logic programming and caused her to go haywire. Several lower level Guardians attempted to stop her, however she overpowered them easily...and that was when her other half was sent in to shut her down, or bring her in for repairs. As the more trusting of the two, Aerys tried to reason with her sister first, which failed miserably when Ryza refused to go in...and began to attack her. The two were evenly matched, as they knew ech other backwards and forwards, however, eventually Aerys found a slight opening and managed damage Ryza enough to force a repair shutdown...and Ryza did the same to her. The abrupt forced shutdowns damaged both Guardians' memory files, and due to certain circumstances, neither girl's systems managed to make a full recovery, either.

Which is why the last thing Ryza remembers is leaving the home she shared with Aerys on their homeworld. The next thing she remembers is waking up as her body crashed to the ground outside Shipwrech, with Aerys nowhere in sight. When she tried to think back to what had happened to land her there, she was greeted with splitting head pain, and a message that flashed across her vision: "aNNNNNNNNd $0 1T b3giiiiiiiiin$ @gA1n...."

Abilities:
Built to Protect-Being created with the sole purpose of protection in mind, Ryza is stronger, faster, and just all around better than your standard human being, however she's often hindered by thoroughly fried systems and potentially migraine level head pain. She's occasionally prone to blacking out and going on fits of mass destruction. She also sports an on board repair system that mends most of her injuries. Minor things like cuts and scrapes can take a few seconds to a few minutes, more extensive damage can take days, even weeks, and some require immediate shutdown on Ryza's part to take care of the damage.
Fountain of Knowledge-Ryza was created with a very large informational database inside her "head," and sensors that love to bombard her with questions and pull up useless prompts. The problem for Ryza is that absolutely none of it works properly. Prompts are often jumbled messages composed of a mix of alphanumeric characters and symbols, and she can never seem to get a straight answer when she asks for something.
Networking- Another mostly useless ability, Ryza has the ability to connect to other nearby Guardians to communicate and share information. Ryza tends to use this to gain access to Aerys' working information databases.
Equipment: A scythe she calls Oblivion. It's a bit longer than she is tall, the blade itself bears a notable black hue to the metal, and it's made of one of the toughest metals found on their home planet. She's had it as long as she can remember, and it stays attached to her back through a peculiar magnetic system when not in use.
