Well, let me talk about Serena...
(this is Minecraft by the way so you might mot know a single thing I'm talking about)
So once Steve (the default character) defeated the Ender Dragon (biggest boss in the game), the Ender dragon dropped an egg, as usual. Steve wanted to know what it was like to have a baby dragon, so he took the egg and returned back home from the End dimension. As he took care of the egg, something inside was happening that was very different than what usually happens. If you're familiar with Horton Hears a Who (the book) then you might know what happened; instead of a baby dragon, a baby dragon-human hybrid hatched out. Although Steve was surprised, he took the baby in as his own daughter and named her Serena. As Serena grew up, she was tormented and emotionally tortured by the villagers of the world. However, she managed to stay sane because of her dad, who had always accepted her as who she was. One day, as they were staying in another village, the villagers got fed up of the apparent "demon" living among them and decided to kill her. The captured her and bound her to a metal board. They chose their best archer to kill her with an arrow dipped in a potion of poison. But of course, in comes dad, saving her. He died, but in Minecraft, you can respawn, AKA be "reborn" and everything will still be the same. (You'll just lose all your items). Serena knew her dad would respawn, but she had already gone through 22 years of this torture. She snapped. This was when "Seranity" was born. Notice the word "insanity". her normally oval-shaped pupils (she had violet dragon eyes) turned into thin slits. Scales grew up her legs and arms, and her legs turned into dragon legs. Her tail spikes grew larger and sharper, as well as her fangs. She couldn't think clearly, so she ended up killing one of the village priests...and I don't want to say how. Let's just say it was a violent death. The villagers banished Steve and Serena from their village. As the two were traveling across the plains, looking for a new place to build their home, Serena asked the one question Steve had hoped she would never ask;
"what am I?" Steve, of course, had to answer her truthfully because of the recent...incident. Serena was shocked and scared, especially of herself. She later ended up developing slight PTSD and depression. When they had chosen a place to build their home and built their PERNAMENT home there, Serena ran away when Steve was sleeping. She lived on her own for two years until her house had caught on fire. Of course, being part dragon, she was immune to fire. However, the fire blinded her and she hit her head HARD (and I mean hard) against her enchantment table (made of OBSIDIAN AND DIAMONDS!), causing severe memory loss. She wandered around, and a few months later, met Herobrine. (an mysterious entity in the game, and if I explain HIS backstory, we'll be here for the rest of the week...) And after that...well...it's best if I don't tell you.
