Winged Teacher?

Jason was a little bit confused because Mr. Greil had messaged him over a dozen times.

However, only now could he respond to his teacher.

[I was outside the dome until now. What's wrong?] Jason asked, not knowing what exactly was going on.

[Don't leave the dome's protection for the time being. Something is wrong with these Goblins and we still can't figure out what.]

[Fortunately, nothing happened to you and you haven't met larger hunting groups. Students below the Expert rank are forbidden to leave the dome for the time being!] 

His teacher almost answered immediately and Jason asked himself how his teacher had written the two messages within such a short time. 

Furthermore, Jason had never received so many messages from his teacher which was also new.
