Calm Before the Storm (Part 1)

The purple-gold dragon was very frustrated because its powers were suppressed at level 12, there the city territory was diminishing its powers further, and it had to worry about Grand Duke Iron Blood dying at any given moment. 

It resulted in a powerful, mighty being having to run for its life like a rat, and there were still pursuers coming at them.

It had had enough!

It shot a stream of dragon's breath as soon as it dove. Dragon's breath at such levels meant that it could shoot as much as it liked. That was the benefit of having one's level suppressed to far lower levels—conservation was easy.

When humans spit, there was a possibility that their mouths and throats would feel dry. When dragons blew, the stream never came out in short supply.
