I'm incredibly new to this site so you can take my words with as little or large value as you desire, though I think considering what I'll say, you should eer on the larger side.
I can honestly say that I do not believe that Malum would be the character he has thus far developed, without roleplaying with you. My first-ever thread on Chaos was one with you, and I think in that thread, I found Malum in such a way that I could have never found him, I was able to truly feel how he was feeling, express how he was feeling, all due to how your roleplay encouraged me to go. In that thread, though Malum got absolutely annihilated (indeed he rightfully did not score a single hit on her), I never felt like I was being pushed to the ground, instead, every post was just encouragement to go further, go higher, to never give up, and I think that's a rare and amazing thing to accomplish.
And I do find it odd to judge a character, and then talk about another character, but I think honestly how a character is able to influence and impact the characters around them to be the most fundamental measure of success.
I do not think Malum would be who he is as a character if he was not an apprentice to Darth Ophidia, and I really hope we can continue to write together, and maybe have Malum make even a fraction of the impact that she has made on him!
