Caleb Widowgast [Critical Role]

 Caleb knew he had a tendency to work a little too hard and a little too late when his friends were off on their own pursuits and a certain drow was off doing whatever it was drow wizards on the run did when they had to be on the run.  But Caleb needed distraction when someone couldn't provide it and work was that. 

Currently he was bent over his newest spell book painstakingly copying a delightful sensation spell he planned to spring on Essek when he returned when he heard footsteps stop outside his office door and a soft tap then hit the door itself. Caleb looked up eyes suddenly blurry as he realized how late it was. His students knew how late he tended to work so it was no surprise that one of them might have come to him when they needed some help. 

"Come in," he called out tiredly. "The door is unlocked."
