Hi there!
Arad could meet either of my characters Orion or Briia. Either could work I think.
For Orion:
Could be an amusing meet and greet thread, as Orion is traveling around the universe in his many explorations. Not sure what else could happen or where exactly they would meet but we can figure it out, if interested.
For Briia:
Briia could be on a mission to save a planet (not her own) from a powerful enemy and Arad and her join forces along with some NPCs of mine, that of Briia's people, the Hatuni. The mission could have an epic fail at some point where Briia and Arad get into some major trouble but it will all work out in the end. But not without lots of conflict.
Also, check out my 'Box of Ideas' thread in the plotting center. Will link it in my signature in just a tad bit so it is easier to find.
