Master's treasure

Kitsune's Master isn't answering. He always answers the moment she calls, no matter where he is. So what happened? Being 6000 miles away with no contact isn't easy... So Sten calls. Master Arra's most trusted friend, given the responsibility to care for Kitsune if something were to happen to him.

Why isn't Master Arra answering? How does Sten deal with his given role as secondary master.

(This was really a test for me to see what a secondary master would do in certain situations, how he'd have to react. The concept is new and strange to me especially because i'm very territorial. So why not try and write about it to try and understand it better.)
