Okay! Post is up! Also, to clarify, the sellsword is a petty magician who can do some elemental magic. As I mentioned, magical ability is distributed in a bell curve, so the overwhelming majority of people have some level of magic - those who are totally devoid of it are as rare as those who have incredibly high amounts of inborn magical ability. Whether Devon is one of those unlucky few who really can't do an ounce of magic is up to you - or his could be some kind of esoteric and basically useless magic, like minor illusions, extremely weak teleportation, or the ability to telepathically talk to songbirds.
I just figured that the divide between our two physical-based fighters and our two magic-users would be significant enough even if the former two do have some level of magical ability - to be readily called a 'magic user' would imply one has enough magical energy to actually use a significant number of spells on a daily or near-daily basis, as a wix or mage or warlock would, whereas a petty magician wouldn't.
Also, I figured your witch might be tromping through the forest and happen too close to the sellsword's camp, or she might've been trying to make an approach - that's up to you. Let me know if you had something specific in mind, I can always edit.
