Oα-βκδ

(anglicized as OA-BKO) is a dimension that takes place in the modern day, but with medieval technology. The reason why no modern or even semi-modern technology exists in this dimension is explained below, along with explanations of various locations and characters that exist in this universe.
== History ==
During the events of Sonic Heroes, Sonic and his friends fought Metal Sonic, who had gone rogue, become ultra-powerful, and was now trying to destroy the world. Sonic and his friends succeeded in defeating Metal Sonic, but wound up accidentally destroying him. This activated a failsafe that Metal Sonic had built in that disabled all modern technology, as Metal Sonic figured that, if he was going to lose against Sonic, then Sonic could probably defeat any similar technology, making it useless, so he might as well deny Sonic the advantage of having any similar technology of his own to use.
As a result of all modern technology being disabled, effectively putting Dr. Eggman out of a job, Dr. Eggman disappeared. While Sonic and most his friends moved on from fighting Dr. Eggman and tried to find other things to do with their lives, assuming that Dr. Eggman had decided to stop fighting them, Shadow—who had avoided being disabled by Metal Sonic due to Shadow being an artificial life form, not a robot—was suspicious of this sudden disappearance and decided to search for Dr. Eggman to see what he was up to. Upon finding Dr. Eggman, he discovered that Dr. Eggman had spent his time using his skills to create high-quality weapons and armor while slipping under the radar. Shadow managed to escape unnoticed, but decided not to alert Sonic or most of Sonic's friends, as he doubted that Sonic or most of Sonic's friends would believe him. Instead, he went to Tails and got Tails to start using Tails's own skills to build good weapons and armor to rival Dr. Eggman's, as Shadow realized that, when the time came, Sonic and most of his friends' skills wouldn't be able to match Dr. Eggman's weaponry and armor. Shadow also continued spying on Dr. Eggman to get more information.
Shadow's efforts were vindicated when Dr. Eggman decided to come out of hiding, hired a number of workers to suit up, and sent them off to try to take over the world. Sonic and his friends returned to try to fight off the soldiers, but their efforts proved mostly useless, as Shadow had suspected. Once Shadow saw that Sonic and his friends had realized that they couldn't fight Dr. Eggman, Shadow informed Sonic and his friends of the stash of armor and weapons that he had had Tails build up, as well as of the fact that Shadow had obtained a significant amount of knowledge on Dr. Eggman's plans. Due to the combination of these two facts, Shadow was able to assemble the other heroes as a team of knights under his own command. However, the heroes were still unable to defeat Dr. Eggman's troops as quickly as before, due to the heroes' lack of expertise with their new armor and weaponry, as well as the fact that, with living troops who he could recruit regularly and only had to outfit with armor and weapons, Dr. Eggman was far more powerful than before. Thus began a lengthy war between Shadow's Knights and Eggman's Army.
== Locations ==
Please ask me, Wikikinetic, if you want your character to live anywhere in this dimension. If I say yes, you can add your character to the appropriate list below. Also note that, as of now, all of the locations in this list are in South Island.
=== Green Hill ===
A grassy plain full of palm trees, loops, and cliffs. A perfect place for constructing a base in relative cover, as well as for practicing various athletic feats. The base of operations for Shadow's Knights.
==== Notable Residents ====
*Shadow the Hedgehog: The leader of Shadow's Knights. While he tends to come off as cold and calculating, he also has large stockpiles of valuable knowledge, allowing him to make plans better than anyone else on the team…which is why he's in charge. Shadow is also the most powerful member of the team, due to his expert swordsmanship and his possession of Chaos powers.
*Sonic the Hedgehog: The second-in-command of Shadow's Knights. Sonic is much more charismatic than Shadow, but his general recklessness makes him less suited to leading and more suited to fighting than Shadow is. However, Sonic is pretty good at boosting morale, hence his position as the second-in-command.
*Tails the Fox: The blacksmith of Shadow's Knights, Tails doesn't tend to go into battle with the others, instead staying back to make extra armor and weaponry for the fighters and to repair armor and weaponry when it gets broken. Personality-wise, Tails is sweet, but shy, preferring to stay in his forge and not get involved in confrontations.
*Silver the Hedgehog: The communications agent, Silver uses his telepathy to let the Shadow's Knights members communicate over long distances. Tends to be optimistic, but is also possessed by a burning desire to not let the world fall to the same fate as his own world. Also the only one of Shadow's Knights not to use a physical weapon, instead relying on his telekinesis to fight opponents.
*Rouge the Bat: The team's compiler of knowledge, Rouge's job is writing down everything important in one of the many books of such data in the Shadow's Knights HQ. Like Tails, Rouge doesn't fight with the others, but she is far more vocal in team discussions than he is. 
*Andy Blackwell: A member of Shadow’s Knights, who doesn’t seem to like the other knights very much, with two exceptions; Platinum and Shadow. She’s pretty aggressive, but isn’t an outright bully. But she still likes teasing the others by being overly sarcastic. She admires Shadow as a great leader.
*Platinum Larin: Another member of Shadow’s Knights, and Andy’s best friend. He’s a risk-taker, running into situations head-first. He doesn’t understand why Andy likes Shadow so much, as he finds Shadow boring and strict. However, unlike Sonic, he isn’t reckless, just very stubborn.
=== Bridge Rapids ===
A series of rushing streams surrounded by high cliffs, with several bridges constructed to connect the cliffs. This is the main area where battles occur between Shadow's Knights and Eggman's Army, as Dr. Eggman favors it for its narrow bridges, which make it easy to corner fighters and force two-versus one fights, and Shadow's Knights find it to be a better battleground than the nearby Green Hill.
==== Notable Residents ====
As of right now, there are no notable residents of Bridge Rapids.
=== Waterway Jungle ===
A jungle filled with waterways, which Shadow's Knights use for quick travel by boat. Used by Shadow's Knights, but not by Eggman's Army, both due to its treacherousness. A portal is generally kept here to give Knuckles quick access to the location of the Emeralds, but to allow him to seal it if he needs to do so in order to protect it from Dr. Eggman or other threats.
==== Notable Residents ====
*Knuckles the Echidna: The guardian of the Chaos Emeralds and a member of Shadow's Knights, Knuckles balances the two by camping out in Waterway Jungle, where he can both keep an eye on the Chaos Emeralds and help Shadow's Knights if need be. A firm defender of justice, if a bit stubborn.
*Big the Cat: A fisherman who persistently lodges and fishes here, despite the incredible personal dangers in doing so (which are frequently pointed out to him by Knuckles). Very calm at all times, but even more stubborn than Knuckles, refusing to break his routine at any cost.
=== Labyrinth ===
A maze-like area with abundant traps, waterfalls, and other hindrances to movement. This area is sometimes used by Shadow's Knights for launching sneak attacks on Eggman's Army, but only occasionally, as it is very difficult to navigate.
==== Notable Residents ====
As of right now, there are no notable residents of Labyrinth.
=== Marble Ruins ===
An area filled with marble ruins overgrown with grass and containing lava in odd parts of the ruins. It is habitable, but is somewhat dangerous, and so is mostly unpopulated. It's also dangerous enough that even Shadow's Army will only rarely use it as a navigation route. Blaze likes this area, though.
==== Notable Residents ====
*Blaze the Cat: A member of Shadow's Knights, and a bit of a loner. Hangs out here to test her pyrokinetic skills on the nearby lava. Probably the second-strongest of Shadow's Knights—after Shadow himself—due to her pyrokinesis, but no one has ever tested this.
=== Starlight City ===
The main settlement for the civilians of South Island. Most of the technology doesn't work any more, but the buildings are still livable, so it is generally considered the best place for civilians to live. Occasionally, either Shadow's Knights or Eggman's Army will try to recruit some of these civilians, with decreasing success (as the civilians interested in doing this have increasingly joined forces with one faction or the other, decreasing the number of interested civilians).
==== Notable Residents ====
*Amy the Hedgehog: Formerly a member of Shadow's Knights, Amy left when she got bored by life as a member of Shadow's Knights. Enjoys her life here as a normal person, but doesn't mind the occasional battle, as she still keeps her trusty mallet on hand and appreciates the exercise. 
*Cream the Rabbit: A timid young girl who tries to live normally and keep her head down in times of battle. Also a friend of Amy.
=== Mountain Base ===
Created when Dr. Eggman's Sky Base ceased working—caused by Metal Sonic disabling all modern technology—and crashed into Dr. Eggman's other base, located at the top of South Island's mountain. Despite the fact that barely any of this base's technology works, Dr. Eggman uses this as a new base, still finding use in this due to the large amounts of metal here and in the shelter provided by the remaining structures.
==== Notable Residents ====
*Dr. Eggman: The main enemy of Shadow's Knights and the leader of Eggman's Army, Dr. Eggman is the main antagonist to most of South Island, including some of his own Army members. Also serves blacksmith duties in addition to his leadership role.
== Fun Facts ==
*This dimension's name is obtained by taking a five-letter acronym—Shadow's Army Black Knight Dimension (where Shadow's Army alludes to Shadow's Knights and Black Knight alludes to Sonic and the Black Knight, the game that this dimension was loosely based on)—and turning each of this acronym's letters into a Greek letter, obtaining .
