Another great chapter! Your description of how Celsius builds up his ember attack, and how he figures out a way to make it work for him is awesome. Nick's backstory filled in some of the blanks. I had to laugh at Sen's encounter with Zara - I know people who talk like that, and take themselves seriously! It was cool seeing Nick beat her Dragonair so thoroughly!
It'll be interesting to see what Charlotte does, and how the green-haired stranger affects things.
You are a wonderful writer. Keep it up!
