Shadda had sent the wall towards her opponent, sending him backpeddling away at the usually 'oh crap run' human speed. However what was a surprise to Cahrtikan(considering Shadda didnt know what to expect to happen) was that the opponent opened a black hole to counter the attack! 

Something he noticed was that it obscured Scion from both his and Shadda's vision. And then her attack...vanished?

Suddenly the small girl was constricted from behind, and became unable to move in her standing position.
"Let me go!" She yelled at her unseen enemy.
[Shadda, he's not touching you, release your magic.] He said in his calm tone.

Shadda then tried to release her magic, still not knowing where Scion was.
