Well written. My group and I had fun with it. The part about magic users being enslaved could have been left out and that would help DM's to incorporate this into their own preferred setting. Also Obstacle 3 in the chase was a little hard to implement. Problem came in deciding who just dropped down and who tried to do it with an athletics check to avoid damage. The way I implemented the suggested inspiration section was to tell them that one of them was hired by a rival house to gather info on house tors underground dealings. We had fun with that. Good work.
