Smajor has a problem. I call it siblings. This man is canonical made siblings in MANY ways. Here's a few.
Scott and Xornoth- from Empires smp season 1. They weren't canon to be siblings, though their relationship wasn't the best. Scott didn’t know he had a brother for a long time, and then was destined to fight and kill him to protect the Server. At the rapture, he kills himself, also killing Xornoth, but both are sent into a parallel universe where the two could finally be brothers.
Scott and CaptainSparkelzed- from orgins smp. This isn't canon, but both had the starborne origin.
Scott and Lauren- from YouTube and afterlife smp. The two are really good friends on smp's like: One Life, Kingdom Craft, Afterlife smp, and more. They were made siblings because of their great friendship. They are often called the galaxy siblings, from a gacha react. Scott has cyan hair with blue eyes while Lauren has Purple hair and purple eyes.
So. Here is how I think his family should be, with the addition of some other headcanons I make.
Sparklez is the oldest sibling and is a Starborne, he keeps everyone in line. Xornoth is the next oldest, by a few years. He is the emo introvert of the group. He is an elf, but still has the vine/corruption powers. Lauren is the next in line. She likes baking bread and has lots of pet chickens. Oli(orionsound) is the next in line. He is a theater kid who loves music. Like Lauren, he is a full enderian, but a albino enderian. He also was gifted the Orb and will kill anyone who touches it. He is slightly younger than Lauren, but she treats him like her baby brother. She is very overprotective of him, though she won't join his weird Orb cult. The last, and youngest, is Scott. He and Lauren has a love-hate relationship. Oli and he take theater together, and they bring the tea and drama to the group. Scott is Xornoth's favorite sibling, though he would never admit out loud. Xornoth can and will kill someone if they hurt his little brother. Like Sparkelz, he is also Starborne but is an elf like Xornoth. He looks like an elf, but doesn't have wings and has a fluffy tail. Scott is a bit jealous at Sparkelz for the being the 'Star prince', a title he really wanted. Scott as the youngest has overprotective siblings and is very spoiled.
These are headcanons for his family, but I like to mention two headcanons from two authors. TheWritersHeir headcanons Lizzie as Scott's adoptive sister. Xornoth and Scott adopte her. TheWritersHeir headcanons Kristin as his sister. They are blood related in her Home again, home again series.
