Aster kept himself hidden so that the kidnappers wouldn't unintentionally find him. At the same time, he was observing them, keeping track of every member present.
'Twenty-eight kidnappers and 7 captives...' He counted in the end.
All the kidnappers were men with tough-looking builds, making it a little scary for Aster to think about what he was about to do next.
"Phew..."
He took a deep breath while keeping track of the time.
Then, when there was only a minute left, he began to move away from the camp, about fifty meters in all, before closing his eyes. Soon after, the carved seal on the back of his right hand started to release a faint glow.
It wasn't bright enough to attract unwanted attention, thankfully, so he could concentrate without getting worried about interruptions.
"... Now!"
When his mental timer reached zero, he started to wave his hand forward, commanding the seal on his arm.
