No, anybody an apply there. Just read it a bit (you might 'threadstalk' Teja, for example, to get a point of reference, keeping an eye on his tagged entries; or indeed any other character, to narrow things down a bit) and then, when apps are open again (from the 1st to 7th every month), you app somebody that you want.

I might tempt you with Myrtia (the 'girlfriend went stabbity', you know), but to be honest, narrative causality is so strong, that between he 19th century canon, and the 21st century values of Milliways, her plot line is completely on rails; she has what one would call insta-plot, and not much freedom in her development, should she come to Milliways. On the other hand, she'd be easy, for a first character; her canon is limited, you know all there is to it, and you couldn't do much wrong with her.-
