Long, long ago Satan and God decided that neither had time to make sure the balance of life and death was kept, nor did they really want to let the other person be in control of something so powerful. And so, they decided to collaborate on creating a new being, as to make sure that they had equal influence in the matter. This is actually one of the only times they have ever put their differences aside to do their job.
The creature they brought to life was the Deity Khaal - a being neutral being, meaning it was neither holy nor unholy. Khaal got a lot of freedom to do as he pleased, as long as he took care of Life and Death, which back then was considered to be very connected and therefor the same.
With time Khaal mingled with other neutral deities as they were born into Rhelicha in different ways. He found them easier to get along with and as a rule of thumb, he helped them get comfortable as a deity, as his influence stretched far and wide. One of these other old deities was Aquaaris, Mother of the sea. THough Khaal was older than her and he helped her a lot, Aquaaris' motherly atmosphere shaped their relationship a lot. Having no other parental figure and often feeling drained from his duties, Khaal found a lot of comfort in her presense. Together they closely collaborated on multiple projects - She helped him make Kiilve, a waterfall in Khaals garden, whose water extended living beings' life. In turn, he blessed her so that she could fill any body of water with life, despite the hard enviromental issues. Life would find its way, even in the deepsea, where the pressure in the water was harsh or in the saltiest of lakes, where fish had a hard time adjusting.
Despite how much Aquaaris loved to create, she could hardly control and take care of all of it, and so to help her she had five daughters. One of these daughters, Kraken, was in general resposible for cephalopods. She was quite chaotic in nature and so her creations reflected that many of them growing to be feral in nature.
Despite a rocky start of many hundreds of years, Khaal and Kraken soon found that their opposite personalities was quite matcihng - Kraken challenged Khaals very introverted nature and Khaal in turn offered stability. The unlikely pair fell in love, though this relationship wouldn't sail for as long as Khaal had hoped. It's a bit hard to find good sources on what happened - Khaal isn't inclined to talk about the events himself, however the stories that is told on goes something like this:
Kraken was still very wild and unruly, but as this softer and kinder love with Khaal grew, she found herself unable to live in the same enviroment as she had before. The wild and chaotic offspring she had brought into this world was too feral and unused to her newfound soft nature. Finding so much joy in giving back to what she loved, she didn't hesitate when her children wished to tear her apart at eat her. To her, it seemed perfectly normal, like how the octopus mother also becomes food for her kids, in order to help them grow. As a deity, the concept of dying was not one Kraken understood nor cared to understand. Nothing was as important as to dive headfirst into her new passion; to unconditionally give onto what she believed in, purely out of love.
Khaal was devastated over her loss, without her vessel, he couldn't bring her back to her own self, unless he was to made her a new one. In his heart however, she knew she had done as she wanted and as much as it saddened him, he respected her choice to do with her live as she wanted.
After Kraken was gone, he didn't have the same energy to continue the work he had done since the dawn of time and so he distracted himself by taking someone under his wing - someone who could be trained into taking the role of balancing death, so that he only had to focus on life. Some say it was because of the loss of his loved one,that caused that part of his job to feel much too heavy for him to continue bearing. The person he chose as his apprentice was the 1st Death, Ehlyze. Years and years passed, his sadness slowly faded as he found a lot of calm in his job and nturing his garden. One day he decided to find out where Kraken's soul was. Despite the fact that she had been dead, her soul had to be reborn into a new vessel - someone who wasn't the partner he had once had. Even so, as a last symbol of his love, he wanted to offer her soul immortality, something she once had, but no longer was guaranteed.
Very befittingly, he found out that her soul had been reincarnated into a chaotic cecaelia, Raboraska. He was wild, powerful and eager to create in his own ways, very akin to Kraken. It felt easy for Khaal to offer Raboraska immortality for though he was very aware they were not the same, he found the same traits endearing in Raboraska. And though Raboraska didn't remember their life together in the past, he seemed very excited around the deity.
Khaal offered Raboraska a magical ring that would protect Raboraska from dying, which Raboraska in return relentlessly joked made them a couple, in part due to the lingering feelings his soul had for Khaal. As Khaal didn't really seem to comment on it, Raboraska just assumed that that's how it was, offering to give Khaal a ring in return, though also noting that those weren't easy to put on a hoof.
Ever since then Khaal and Raboraska has grown close, not quite in the same way as Kraken and Khaal did, but with time of getting to know each other, Raboraska puzzled the story together and heped Khaal mend years of untreated sorrow. They grew very close and in time Khaal came to adore Raboraska in his own way. He wasn't Kraken, and that was fine. Nothing could really replace her. Instead, he got the oppertunity to once again to feel the joy of finding someone special to share life with.
