Toxicology professor Caduceus Clay has tenure at Wildemount and loves helping in the school greenhouse. He also gets along well enough with some of the other professors and generally is fine with his little garden life and couple of friends. Then he actually meets Veth "Nott" Brenatto's, fellow professor and proclaimed BFF Caleb Widogast.
History professor Caleb Widogast has a fun time dabbling in science and teaching with his friend Nott, but not so much dealing with students outside of his posted office hours. He understands that there are things outside of his books, his two friends, teaching, and his cat but didn't reach for such things till he met fellow professor Caduceus Clay.
