As you can see I changed a lot of things and added some things too. If I do end up winning, I plan on making him Magnus' older brother. It's kinda why he has the same necklace as him. I also decided to rename him, instead of Crescent, his name would be Seoli and his snake would be named Luni. About the snake, it's existence is similar to Magnus' pet Lapiz. Luni is apart of Seoli just like Lapiz is a part of Magnus. Seoli's relationship with Magnus would be kinda like your standard sibling rivalry, they love eachother, but they bicker a lot. Nightmare has to make them get along and scold them if they act up.

Bonus:

A small doodle of Seoli teasing Magnus about something ;3

Seoli would be an anti-social and cold perspn towards most people, but he's softer with his family. He is very attached to his mom, Nightmare may be grumpy, but Seoli loves him. Seoli loves Killer too, and they often go training. Seoli is pretty tall compared to his brother, he's around 15 years old, and is 5'4(he wears high heels to make him taller). He is pretty much like Mirage, but even more scary and an asshole. He's got a dark humor and will make somebody's life hell if they hurt his family or his little brother. Yeah, he's scary.
