You know i think the characters who really dont have a part on MALACHOR, are visas hk mandalore t3m4 and atton. But attons my favourate because he cracks me up, hk is too badass, mandalore and visisa are important on the ravenger but t3 is just a droid who only can be important 1nce. (taris and peragus.) also, check this
and scroll down to the scripts. Might find useful.
