Caethir

This crotchety, bony old man has little respect for warriors and others of martial disciplines, no respect for those significantly younger than himself (which is anyone human), and an intense dislike of any fellow spellcaster who hasn't 'honestly earned their powers through practice and study'. He speaks with a gravelish growl and walks with a distinct limp. His laugh is a wheezing, wretched sound that usually ends in him coughing wetly.

The reason the guild continues to tolerate this thoroughly unpleasant individual is simple - with Rhillaine gone, he and Rin are two of the few Guild practitioners of the arcane able to cast teleportation spells.
