Dragon Prince at the Academy of Witches

Inadvertently, I helped our world with mysterious dangerous creatures, and they arranged a hunt for me. And the Dragon Prince came to the Academy! I had absolutely no case before this, until my secret familiarity fell into the Dragon dessert, and he did not consider me involved in the attempt on his murder.
Involuntarily, the prince and I witnessed the conversation about the upcoming riot. Someone wants to start a war between dragons and witches ... And only the prince and I can reveal the name of this mysterious conspirator. But we have too different ways and goals with the dragon ... Will it be possible to unite for the sake of a common goal?
And will it be possible to return the monsters from someone else"s world back?
