Cool, sounds like a fun group of characters. Personally, I relaly like involving my own characters amongst one another. Before Dorann became the Grand Imperator to the Chiss, he and Oonoo the Celegian were Command-Partners in the military. Hazac (before becoming Darth Vendis), has been training my Acolyte, Kel Magna.
I can't wait to see your character profile once it's ready :D
