The second class went smoothly, and as 3 pm approached, Kellen felt exhaustion fill him. Brent had left him to go do his round of guiding, after Kellen had shoved him full of shakes. And after taking a few moments for himself, he set to work. 

He only had two hours before he had to go meet up with Rhys for his guiding session with Taylor. So he'd better put his head down and get to work. 

Kellen had already reached out to all of the Guiding Centers in the morning, and by mid afternoon, he'd had varying responses. 

Of course, Guiding Center B had responded back first, and quickly at that. They were very straightforward in their willingness to help out. Guiding Center A had sent a very lengthy response, full of fancy words, and several insults, but at the end had also agreed to help.
