For the briefest of instants Arazni is very alarmed!

Iomedae’s sword is out of its sheath and between her and the new arrival faster than an ordinary human can even perceive motion, but she does notice Arazni laughing, and is also supernaturally good at reading people even if they happen to be tiny adorable horse-creatures, and while it’s facially ridiculous she also has an immediate guess about who the tiny adorable horse-creature corresponds to in some bizarre metaphysical sense. It’s not Arazni.
“As your commanding officer—” she manages to get out between bouts of laughter “—this was a poor use of a planar binding spell—but—well played. Well fucking played.”
