Amber's life, huh?
Well, there's a decent cast of characters here to choose from, beginning with Amber's friend group and younger sister:
Ethan Walker:
Reserved, polite, and deeply caring for his friends, Ethan struggles to show this care for his friends. The only one aware of his struggle is Amelia, his best friends of many, many years. Straightforward with his words, Ethan likes to hear all sides of a story before making up his mind, unlike Amber and Amelia who prefer to strike first, figure it out later. He has a severe fear of heights and rollercoasters.
Ethan has the potential for magic, but without proper training, he cannot use it. His only uses are as a neutralizer, allowing him to nullify any spells and curses that are being cast, or as a battery to allow a more powerful caster to use more spells.
Amelia Hayes:
Hotheaded and loud, Amelia acts as Ethan's opposite within their friend group. She makes her opinions known to all around her, no matter how controversial they may be. She will fiercely defend any of her friends, with fists if needed, and rarely backs down from any sort of fight.
Amelia has no magical potential, but if she figures out that it exists, she does have quite a powerful physical caster as a friend.
Cassandra 'Cassie' King:
Childish, highly adorable, and easily excited, Amber's younger sister adores everyone and everything she comes into contact with. Rare is the person who doesn't immediately dote over this lovable cinnamon roll, and even Adam and Alisa aren't immune to her charms. The only one who doesn't fall prey to her adorableness is her own sister, who doesn't see what all the fuss is about.
Like her sister, Cassie has the potential for magic. She has just recieved her first grimoire, however, meaning she can only cast basic spells, but she does show an affinity for protection magic.
Or maybe somebody else from Amber's life?
