The Akai Amulet
It is recommended that you post a back story and description here, similar to that of Grittinius.
Sylvester is the son of Amadeus and Natalie Tails. He was accepted into a prestigious magic academy, but constantly got into trouble for ignoring his studies and focusing all his energy on learning incredibly destructive and advanced spells. He eventually fled the school with a huge book of advanced spells. The school put out a bounty on his head to get the book back. A whole bunch of people are after him and he became a bounty hunter and stuff. All the fire he casts is purple.
