Monday morning classes started normally enough. William made it to Magical Theory on time despite his body still protesting from yesterday's training session.
Professor Ashcroft was lecturing about essence flow optimization when William's attention drifted. He'd heard this material before during previous study sessions with Lyanna, and his new trait made the concepts feel almost intuitive anyway.
He was pulled back to attention when the professor called on him.
"Mr. Cross, since you seem lost in thought, perhaps you can explain how secondary essence pathways differ from primary channels in terms of flow resistance?"
William stood up. "Secondary pathways have roughly thirty percent more resistance due to narrower channel diameter and less developed pathway walls. They're primarily used for overflow when primary channels are at capacity or for specific techniques that benefit from the slower, more controlled flow rate."
