High Commander Karia Bio (+ my version of Kreeyan lore)
The Kreeyan race was created in the realm of Fabir by Kreeya, the protector goddess of said realm, who had been granted the ability to create life in her realm, and thus help build a prosperous society. Nonetheless, she had her own plans.
Just like the once protector god of Outworld, Shao Kahn, Kreeya wasn’t satisfied with her position as an agent of the Elder Gods. She didn’t like dedicating her divine power to the protection of mortals, she saw herself above them and only considered them worth being pawns in her path to glory, her path to become the most powerful being in all realms. That ambition led her to prepare the Kreeyans, her own daughters, to treat her like their superior, their queen, since they were created, and to start taking over other realms in her name. Karia was among them, and since she proved herself a talented warrior and leader, she had a high position in the Kreeyan army.
Queen Kreeya waited for the right moment to initiate her attack. After Shao Kahn’s failed first invasion of Edenia, she tried to take advantage of the weakened state of Outworld’s army to take over that realm and with that eliminate one of the greatest obstacles for her objectives. This betrayal to her position made the Elder Gods take her divine powers away, just like they did with Shao Kahn when he joined Onaga, but Queen Kreeya was prepared for something like that. She had developed a powerful magic capable of replicating her powers to create life to keep (even if more slowly) expanding her army.
Queen Kreeya’s plan completely backfired, nonetheless. Shao Kahn’s warriors were able to defeat the Kreeyans in ten consecutive Mortal Kombat tournaments, which not only prevented the Kreeyan army from invading Outworld but also set them as the next realm Outworld’s army would invade.
The desperation made Queen Kreeya reveal her true colors. She constantly threatened her own daughters, and forced them to keep fighting despite their fight being already a lost cause, which caused countless unnecessary deaths among them. This made many among them, such as her oldest daughter, Vorpax, and Karia, to grow resentful of their mother for the pain she was causing to their sisters. Karia in particular ended up taking the first possible chance to turn against her.
When Karia’s troops were about to meet in battle with those of the young General Reiko, she offered her surrender and alliance in exchange of freeing their sisters from Queen Kreeya. Seeing Karia’s potential as an ally and a golden opportunity, Reiko accepted. This was one of the events which allowed Reiko to have one of his greatest achievements, managing to invade Queen Kreeya’s castle, slaying the wanna-be conqueror and effectively finishing Outworld’s conquest of Fabir.
After that, while Vorpax became the new queen of the Kreeyans and accepted to serve Outworld’s Empire to protect her sisters, Karia served the Kahn Guard, immediately being given a high position by Reiko due to her assistance in defeating Kreeya. Although initially motivated only by benefiting her sisters through her service, Reiko eventually earned her respect and genuine loyalty due to his abilities and the good treatment of his soldiers. She came to believe that the Kahn Guard under his command could be what Kreeya wished to be in her egomaniac dreams, someone who would unite all realms under a powerful glorious Empire, what Karia had been prepared to create and wished to fulfill.
Karia has been serving under Reiko for more time than most, and her achievements in the battlefield have earned her the position of High Commander among his troops, which makes her an authority just below that of Reiko himself. She will be one of the greatest enemies for anyone who opposes the Kahn Guard.
