"Acrypha?" Talon looked at his companion with confusion when he noticed her grave expression. He didn't understand why she was acting like this when she was fine a second ago.
However, the girl didn't reply as she kept staring at the sky for a while. Her eyes flashed with a weird glint as she finally looked down and said. "Get ready."
"Huh? Ready for wh-"
Before Tlaon could even ask what she was talking about, he felt a chill run down his spine as he heard a small noise. It was a very faint one, barely audible even for his heightened senses. But, he could easily identify it since it was a familiar sound.
'A heartbeat?' He asked himself as he listened quietly.
*BADUM*
The second time was a little louder than before and so was the third time and on forth. The sound of heartbeats echoed in the vicinity. It didn't sound like the heartbeats of a human, but they were similar enough for Talon to identify it with ease.
