What? we were out for an hour?!

In the gravely silent library on a peculiar bare wall at the furthest end of the room came a buzzing sound as four juveniles emerged into the room.No sooner had they arrived than the large wall clock chimed. They darted their eyes in the direction of the clock and alas! their eyes widened in shock at the time displayed. 

"What! We were out for two hours?!" they gasped in unison, their feet glued at the same spot. 

"It felt like days in that dark portal!" murmured Zyda. 

"Let's rest up for the day guys. We shall meet up later," suggested Rolam.
