On the first week after coming back to the server I had an entertaining encounter in the Omicrons with K'Hara, but ever since it's only been two lines of half arsed roleplay and then the blue message harvest.
I'm no expert in K'Hara IDs, but you are allowed in Conn, right? Perhaps you should spend some time there, blow steam off, and then come back to Sirius and attempt to engage in bare minimum roleplay.
I get it, you're playing a killy faction, but encountering a K'Hara while flying TAZ in the past was an exquisite treat. Now it's just a 10 sec countdown till respawn.
