Hello.
He doesn't have a route just yet. At this point you are basically just meeting the characters. The only ones that have a longer introduction are Silas and Aldric. The routes will start on day 3 which is not yet released, but will be hopefully in a month or two. There's also a guide if you were wanting to see the possible options for Orion released so far.
