At present, I have no plans on players dominating Frost. His brother, on the other hand...
Mikhar is not within my jurisdiction; that will be up to the author to decide. As I understand, there is something planned in regards to him, though. What that ultimately turns out to be is a mystery.
I had intended Tarragon to be more of a switch, and the guy absolutely loves to get touchy-feely with dragons. He'll probably be in the loving, intimate side.
Other projects are in the works that'll allow players to be more dominant. I do have one in store, at least.
