I have a very long term goal in mind, and have had it since the creation of both Thurion and Thyrian. They are brothers, and were separated by death when still children. So naturally, they must be reunited at some point. This will be the climax of their story. Once it happens, anything's possible.
For Thurion, I know he is going to at some point in his life return to the Jedi, who he abandoned in order to come with his then master, @[member="Asha Seren"]. Becoming Jedi Master is something I wouldn't disapprove of, but it is in no way mandatory. In his twilight years, I want him to open an orphanage on Coruscant for children of all ages and backgrounds. His story began with the burning down of his home, and it will end with him building a new one. Having @[member="Kida Ravos"] by his side this whole time helps too. :3
As for Thyrian, he died at the hands of the Army of Light during 'Operation: Hammer', and only recently (today, in fact) he was raised from the dead once more, this time into human form, and has retaken his place at his master's side. There are several things still to be occur in his story arc, such as the reunion between him and Thurion, of course. I won't go into spoiler-territory, but most of it involves @[member="Darth Kyros"].
