So with Mathilde being a major shareholder of the EIC
The Hochlander being the company's all-around troubleshooter
And Eike (correct me if I'm wrong) standing to inherit Wilehmina's shares
That's three Grey Wizards in one megacorpo trenchcoat
... Is this the Shadow Wizard Money Gang I keep hearing memes about?
Sort off.
See, there's the original* Shadow Wizard Money Gang, called the Bursar (singular, for complex historical and cultural reasons). They went around bullying Shadow Wizards about money. Very successfully so, actually.
Now, one of the side effects is that just about every Shadow Wizard makes a Money Gang eventually. But it's mostly small scale, single wizard operations. You get bullied if you have too little, but also if you have too much. Weird, but those are the rules of the Bursar cartel**. Anyway, that means there's actually dozens of Shadow Wizard Money Gangs, even if most aren't huge operations.
Now, the EIC stands out from the other Shadow Wizard Money Gangs in the Bursar cartel for its size. Big reason is that it originally was just a Money Gang, with a Shadow Wizard member, so the bullying rules were different. But then later that Shadow Wizard kept getting bigger slices of the Money Gang, so she eventually hired another Shadow Wizard, so it wouldn't run afoul of the rules of the Bursar, around the time it transitioned into undeniably being a Shadow Wizard Money Gang. This is expected to continue into the future, where we'll see more Shadow Wizard and more Money in the gang, but it's still a lower Wizard ratio than other Shadow Wizard Money Gangs.
*Technically there were likely earlier Shadow Wizard Money Gangs, but we know little about those. The Bursar was the first to bring all the Shadow Wizard Money Gangs under control, so they're the first (and so far only) to be able to claim to be
The Shadow Wizard Money Gang.
**And to be fair, they've been doing decently well under those rules. It's been a long time since the internal Wizard Money Gang conflicts against the Gold Wizard Money Gang or the Future Wizard Money Gang, or a big gang war against the Hammer Priest Money Syndicate.
