Simeon is the sage of Practical Magic. As a teacher, he can be a little picky about form and precision when spellcasting and potion making both, but he is always happy to teach, as long as the student is willing to put in the effort to do the job properly. He's not much good at suffering foolishness, but he is old enough to be capable of telling the difference between foolishness and a lack of practice or skill.
He comes from an older family of spellcasters, though not one of the ancient and well-known ones. He was trained from a young age, and his becoming sage was a surprise - but it was also an honor. He considers himself to be friends with both Morgyn and L.
