[X] The Con Is On
No need for an explanation. Gaslight, Girl Boss, Gate keep all these other losers from preventing our divinely mandated right to have awesome powers.
It's for their own good really.
[X] Idea: The High Priestess - Keeper of Secrets
*Theme: Custodian - The High Priestess is the matron of mystery, the connection between the supernatural and the normal and it's deeper, hidden sides are something that are intrinsically known to her.
*Theme: WIthdrawn Involvement - The High Priestess knowns that the benefit of knowing what everything does is that you get to get to act at your own leisure, at the right time.
*Power: Mystic - Secrets come to you like moths attracted to an open flame, only to be consumed and grow the fire. By mere proximity hidden knowledge starts to stream into your mind, at first personal details about a person and then with time and advancement the secrets of the world, the Metaphysicsist, maybe even the Educator will begin to be known to you. After all what is someone once you know their secrets?
Just another pawn.
People will seek you out for your secrets, because gossip is hotter than tea.
*Power: The Link - You are the bridge between the white pillar of Establishment and the black pillar of Strength. You understand that you can only be whole once the binary becomes the duality of whole. You can form connections between people, ideas, concepts with you as the chain holding them together. Two lovers only stay together because you are there to advice them, the sun and the moon give the earth day and night because you are on it, etc.
*Limitation: Je n'ai pas le temps - You are in the know and people seek you out, the other nincompoops in the class are your sycophants and they must be ones one worth your time, not the other way around. As such, you have a tendency to be relatively impassive and must really get off your ass if you want something done the right way. As such you aren't really the really the nuclear go-getter, but that's alright you have other people for that.
*Limitation: Hidden Hand - People like you because know more than them, so it only makes sense that actively telling them the information you would know would only be detrimental. If the world was build on fair and clear communication than it would really be bad. The more you reveal about what you know to others, the weaker you actually get in terms of your power.
*Solomon already has the power of the Mystic, this only plays into his strengths and lets him be even more of a pillow princess. This would play into the Rihaku suggested narrative of Great Teacher or maybe even Sol Bad Guy.
More importantly, it lets us explore the world more in depth! I heard that in immersion you guys didn't get to do that and I like lore, so I don't want to miss out on it here.
*Feat Examples: Find out what the secret of what would motivate the Fool into what would make him into a typical isekai protagonist and link that to him through you. Easy familiar get.
[X] Idea: Judgement - Judge Dredd
*Theme: Judge, Jury, Executioner? - Judgement often suggests introspection and self-assessment of your past and current behavior and then application of such inner values and beliefs to the rest of the world.
*Theme: The Truth can not be hidden - You can only make lawful judgements of the indicted if you know the truth and nothing but the truth, as such why would it not be part of the theme for you uncover it?
*Power: Law-Maker - Create edicts, laws, stipulations. The masses have no choice but to follow them, lest they want to incur the punishment deserving of the crime and there is no worse crime then blasphemy against the Codex and it's holy creator. At first, say that no one except the law giver can eat the Coffee Jello. It's an incredibly strong power to start off only limited well, by the limitation.
*Power: No Lie Told - A judgement made with lack of information or worse, misinformation of falsification is no judgement at all. Some would rightly say it's no worse than the lie that it was founded on. As such as your role as divine Jury it is within your purview to peer through the falsehoods of the world and see the reality hidden beneath it. At first understand as people lie to you directly and then develop it to understand the deeper ambient lies of the world and beyond.
*Limitation: Someone's gotta follow the rules - At the end of the day, the only real limitation is that the rules and precedents you make for punishments for breaking those rules got to happen even if you like it or not, you got to think about all potential ramification of anything you put into a law if you don't want it to be used for evil deeds, or worse...
Against you.
*Limitation: Who Follows the Law in a lawless place? (To be honest as a stipulation I wonder if this limitation is too cringe, I'm on the fence about it but I'm fine about removing it to be entirely honest. Thought I'd check opinions anyways.) - You can only be a judge to constituents that recognize as you such. Simply put, you only need to be recognized once but you still have to be accepted by someone you're trying to impact a law upon that you are the law-giver. No speedrunning capital punishment to the Metaphysicist sadly. Though this works through already established social and power structures.
*This again lets us gain that juicy juicy lore (can you tell I really want it?) and it kinda gives Solomon a catalyst for all his eldritch knowledge to make the world into the better place. After all what is his namesake best known for if not for being the Judge King?
*Feat Examples: If you are a Supreme Justice of the United States you basically rule the country.
[X] Seek the World - Dungeon Master Role
I just like the JRPG villain role more than magic man, sorry.
