Hey guys, I'm the number 10. Go ahead and multiply me. See what happens.
Lord Regius had been in my Inquisitorial Guard since I became Hand of the Dark Lord, and he has even gone to the point where he commanded my own retinue. He is a Master of the Dark Arts, and is only second to myself in its usage.
In the Yuuzhan Vong War, he and two others survived the Battle of Yaga Minor, which saw the Destruction of the White Shadow. He was also at The Maw when I unleashed the Omega Red Virus,
In the Sith Invaison, he commanded one of the strike teams that attacked the Jedi Temple, and slaughtered many Jedi that day.
When I left for the Outer Regions, he followed me and became the Captain of the Inquisitorial Guard, helping me in my many battles there.
At the Battle of Terminus, one of the last in the Sith Crusade in the Unknown Regions, the local population swarmed our position, and managed to kill many of my Inquisitors due to overwhelming numbers. Him and myself, however, combined our Force Techniques and conjured a Massive Force Storm, destroying the City we were in, and all of my other Inquisitors.
Since then, he has been the only Inquisitor I have in my retinue. He is now my "left hand", and is not to be underestimated.
