With Clara focused on Kiruya, Silver quickly made his way through to the back line. There was a squad of combat maids trying to get past Elanor, while the rest were staying on the second floor, providing healing, buffs and long range attacks.
It was prime pickings for Silver, moving undetected through the shadows. In fact, with all the training he has been given, he has reached the point where he can move freely as a shadow even when there are no shadows nearby whatsoever.
Obviously, that would still be noticeable when in a properly lit environment. Still, as long as his path contains the slightest bit of shadows, he'll blend in just fine.
"Everyone should focus on supporting the battle maids! Kiruya said not to worry about her!" Silver approached from the ceiling, learning the enemy's chain of command. There were at least 20 or so maids, each preparing some form of spell.
