So...I have just red mer solarstone's story... (Just found it and had the time to read it)
How dare you make me cry 4-5 times/silly
I love it so much! And oh my god poor sols
And I got a couple of questions! :D
1. You mentioned Earth there, so I'm understanding she is a mer as well? (Mermaid 🌺 ;3) Who was the "darker" mer with her? Under the boat
2. Where did moonstones egg go? I notyit wasn't mentioned after the attack (rest in peace sunstone, we will miss you ❤️🩹)
3. Who was moonstone fighting at the end of his life? (Was it someone random or a specific character that you chose)
It is so cute, and sad and good and Amazing!!! 💖😍❤️
So to start with the fic was written by my good friend @erenevune who also made Sols! (I drew his design based on their description) and so i've allowed them to answer 2 and 3 of your questions which i have copy pasted from discord :D (If anyone hasn't read the fic yet, you can find it here!)
I can answer the first question though!
1. Earth is indeed a mer in the au as well yes! She and the 'mystery darker mer' with her have been in development for a while now and are going to be background characters for the au - i'll be posting art of them very soon so stay tuned ;)
2. Moonstone's egg was killed during the attack that killed Sunstone, despite their best efforts to protect both eggs Sunstone wasn't able to completely block off the attack and Moonstone's egg was the casualty. Though, thankfully, Sunstone died believing he had protected both eggs. Solstone barely survived, it was honestly pure luck Sunstone managed to save even one of them. It was likely either crushed or knocked so hard the baby mer inside was too injured to survive, and by the time Moonstone was able to find his egg it would have been too late to do anything. Very preoccupied with feeling part of him die when Sunstone died, since as twins their life force was connected and Moonstone had to feel every moment of him fading then his sudden absence. The only reason Moonstone survived is because both he and Sunstone had bonded to another mer as mates for their little family pod
3. Moonstone attacked his mate. The mate is unnamed (though I have nicknamed them as "Slate" in my head). After the death of his twin and loss of his own pup, his sanity was degrading rapidly over the years as he was in constant pain from missing half of his soul and greif. He had already been attacking other mers for some time and some cannibalsm had been starting as well. Which, definitely didn't help his steadily shattering mind.
At the end, he completely lost whatever sanity he had left and attacked his mate, killing them and consequently killing himself. Slate let it happen without a fight because they knew all of them would be better off, and that Moonstone had already been gone for a very long time. If not when Sunstone died, then sometime when Sols was still a very young pup. And so had they, just not as badly as Moonstone. They also knew neither of them were fit to care for Sols anymore and hadnt been for years, and while it wasn't a great choice, the mate figured Sols would be better off taking his chances alone.
Was it selfish? Yes. But by this point they were already an absent parent and were looking forward to neither of them constantly suffering just by being alive anymore. In a way, Slate's final act was to protect Sols by making sure Moonstone was focused only on them and would end up killing them, so he couldn't then turn on Sols and kill him too. Sols doesnt look much like Slate, but he does share the same tail fin shape as them.
Sols looks most like Sunstone in terms of colour, but has Moonstones eyes. Physically he looks very much like both Sunstone and Moonstone as they're twins. Though to Moonstone, who was forever grieving, Sols looked more like a mini Sunstone which added to his mental decline towards the end. Sols was a constant reminder of what he lost and why he had to stay, when he would have much rathered to join his twin and pup in death.
