Oh, woah, thanks for the great post! I love posts like these, they really help me solidify things in my own head.
Hiding this because it's so long
Is the MC, in terms of power and control, a genius?
Warlocks in general are a class above wizards because of the innate link they have with the Shroud and your biggest threat is certainly other warlocks. However, the MC still went to a wizard who’d mastered familiar conjuration for advice when creating their familiar. But that master was old and they were only competent in that single field of magic.
Warlocks have an innate ability to understand most magic and will be extra competent in a few. What this means is that the ones you’re really good at are the ones you can use on a moment’s notice, such as in a fight. However, when creating a super persona you have time to think and so you can draw on all schools. So your skill as a warlock won’t restrict what kind of super you can present (yes, this is somewhat gamey, but I thought it important and more fun).
What’s the big plan?
It’s not a monster of the week story! As @SneakyFantasy pointed out, I really should start inserting the mystery earlier. Right now I’m focused on Ch.4 and getting stats sorted, but I’m planning to rewrite some bits in CH.1-3 to hint at the grander mystery. I didn’t really go into it in the synopsis because when I tried to write it, it kept coming out as multiple paragraphs. It’s just kind of hard to explain without understanding the world first! The overall plot is going to be about a mythological, magic problem that’s affecting the mortal world. You’re going to find yourself having to deal with it while the Supers get in your way. Then you can choose whether you deal with them as nuisances or as assets.
Which brings us to being an antihero. You won’t be able to engage in mindless violence just for the sake of it because the plot somewhat relies on you wanting to at least protect either the magical or mundane world (I don’t have the energy to branch it out to a true apathetic path). But you certainly will be able to choose how to handle people getting in your way.
For an example that isn’t in the game: If you need to steal a McGuffin from a museum, some options may be to beat up the superheroes that try to stop you, hire some villains to help you or try to make friends with the superheroes so that they’ll let you get away with it. That kind of thing.
Elza…Sword wielder…Please tell me she is inspired by Erza from Fairy Tail. Please.
Haha, nope, Elza isn’t related to Erza…despite their name and red hair.
is our master a man because of plot reasons?
I can totally understand why you’d want an Izumi mentor, she was awesome. But I’m afraid he’s stuck as a man for plot reasons, sorry. If I let you change that then some important plot points would just become way too obvious.
Having said that, that’s part of the reason Elza’s stuck female too. While your mentor taught you magic, Elza was the one to introduce you to the magic world (a distinction that hasn’t been made clear in the game yet), so she is also a mentor figure in some ways. Eventually, when I find time for flashbacks I hope to explore that more mentor-y side of her but for now you interact as equals.
Again, thanks for the awesome questions! I’m not sure I answered them how you wanted so let me know if some stuff wasn’t clear! Hearing what people want to see helps me understand what options I should present. (e.g. I was worried no one was taking the gun, I’m glad to hear that some people are!)
