Yes. Out of all of the Inquisitors, Marrok is one I found very intriguing. He proved his proficiency in combat during his two duels with Ahsoka Tano and I’m curious about how he not only survived past the Dark Times, but how came into contact with Morgan Elsbeth

It was also implied that he may actually be undead in 'Ahsoka', as the same green magic mist the Nightsisters used burst out of his corpse. It'll be interesting to get an explanation for that

Uggggh, he looks really good in his armor. I would not at all mind seeing more of him, especially in regular clothes.

Let the fanfic flow!

Well, it was said that after Darth Vader’s duel with Ahsoka on Malachor, the Jedi Purge was over, and therefore the Inquisitorius were viewed as obsolete. It’s possible that Marrok was killed by either Vader or in some other battle engagement, then Morgan found his body and used Nightsister magic to revive him. Rather she did this immediately after Marrok’s first death or shortly after being rescued by Baylan Skoll is up in the air.

I don’t see why not

His origins are most likely… born from green magic smoke on Dathomir.

Yes

I guess so sure since he is different compared to the others

I don’t think it’s necessary, he fulfilled his role and we don’t know anything about his character or what could potentially make his backstory interesting. I wouldn’t be against it though as long as it’s written well and doesn’t feel random.

We will see him in Tales of the Empire
