They can be killed. It just usually takes the help of another Pthumerian. I helped Moon Presence to kill Mother Superior in the previous world, though she did most of the work.

[Still, it was immensely satisfying to take a piece out of the old harpy when he got the chance.]

I suppose we shall just have to agree to disagree. Not that it matters much. It took a long time but I gave up the main target of my revenge some time ago.

[Obi-Wan had always been the easier target and it took a long time for Maul to realized he focused on the man because the true desire to take revenge on his master was forever out of his reach. Maul was no longer fueled by revenge now. He had more important things to focus on.]

Duly noted.

[He had enough sense to back off the subject. He hadn't meant it to turn in the direction of a pissing contest anyway. He was just very bad at empathizing with people.]

Hmmm, no, not at all. It explains a lot really.

[Namely how the two of them had become so fucked up. Maul knew he would be very different had he not been raised by such a monster.]

Now now, there are worse things in the world than having a loyal sibling who will stand by you. Allies like that are hard to come by. Back in my own galaxy, it was one of the best things to ever happen to me.

[Maul would have never known what having love from an actual family was like as an adult had his brother not come to rescue him from Lotho Minor and take him home.]
