Just as the two of them were about to scan themselves into the Guiding Division, a loud, long tone could be heard throughout the building. On the other side of the door, loud voices and footsteps could be heard, before the door was flung open, and Casper flew past them. Kellen was pretty sure he didn't even register that Kellen and Brent were there.
Shortly after Casper left, another swarm of Guides left the Division, and Kellen and Brent waited for a second outside of the door, making sure they weren't in anyone's way, before stepping into the Division proper.
It was a mess. Whatever that warning was, it was serious, and had all of the older Guides freaking out. Some of the younger ones seemed worried, but not fully concerned. All except the little Guide that Kellen knew was Casper's assistant simply because he was seated at a desk outside of Casper's office, and was frantically answering phones like his life depended on it.
