Here is my old Kirby I dusted off and reworked, I may or may not add Magolor to my f/o list now
Long ass dump about her backstory under cut (Mostly based off my own hc about Halcandra/magolor here but)
The spunky, lost princess of Halcandra, Estelle was simultaneously outcasted yet pressured into her role of being the princess because of her lack of magic. Tomboyish, feisty and not at all fond of the royal life, she met Magolor, one of the royal mages working in her castle. The two of them became friends and decided to run away from Halcandra, finding the Lor Starcutter in the process and sailing the galaxy. She was always more into science then royal duties, and together with Magolor's inventing skills, the two of them spent their time exploring the galaxy and creating their little gadgets, even sharing childish dreams of starting an amusement park together. It's the life she always wanted, free from all of her burden and pressures of her royal life. Over time however Magolor becoming more and more obsessed with the Master Crown and taking over Halcandra. Magolor too grew up believing that he was never good enough, but he wanted revenge and overthrow the kingdom, as well as the entire universe. As much as she hated her parents Estelle didn’t want that. Believing that he became more power hungry, she left Magolor as he tried to fight Landia by himself and lost that leads into the events of RTDL canon. (breakup arc)
To Kirby and friends during the events of RTDL, she probably looked more like an antagonist in preventing them from getting the Energy Spheres/Ship Parts, but this was supposed to be her preventing Magolor from getting the Master Crown all along, usually with the help of the Sphere Doomers. Over time, they would learn about her and Magolor's true goals. Being with Kirby allowed her to make up with her parents, and she thought that maybe Magolor would do the same. But alas, the Master Crown controlled him like the dangerous object she warned him about. And thus, he had to be struck down. She tried to move on, making a life for herself in Halcandra and Dream Land and helping the residents of both worlds.
..That was until Magolor came back. He did apologize, and while she didn't accept completely, they decided to get back together as friends (Or at least Estelle tried to, cause maybe Mags is starting to realize his feelings for her too late-). Estelle was probably there when Magolor helped Kirby and the rest of the Dream Friends fight void, and now helps him run theme park they always wanted in Merry Magoland.
She’s very sassy, tomboyish and spunky. As an alchemist, her abilities would likely be a repackage version of Doctor, but more "celestial", and she makes the same elemental potions the ability gives you. And also instead of pills she throws gears that can cut things!
She has Dreamy Gear AU Kirby's hat because I made her 3 years ago and I thought "what if Dreamy Gear was a game and the designs from that novel turned into an original character", then I turned her into this. Fun fact, Magolor made the bag she carries with her, along with her scarf
(and she carried them with her to remember him during their breakup arc)
