We discussed you playing a Mage and myself playing a necromancer. We began our trainings and teaching together as adolescence, but I moved onto darker arts, namely necromancy and took on another master. That might be a point of contention for us... we could use that pivotal moment of me leaving as a break in our relationship/friendship - whatever we determine we originally had.
What we need to discuss or really lock down might be why we are coming back together. Is there a war of sorts? Or is there a journey that we must go on together to save mankind or magic itself and in searching for the objects/book (what have you) we really discover each other all over again?
We can start working through this as well.
