Lohrenswald
世界的 bottom ranked physicist
My first thought too.
Anyways, would Sweden care about the religion of its monarch these days? I recommend Lohrenswald convert to Zoroastrianism and marry his sister for a nice hefty prestige and piety boost. He can also then have concubines too for more prestige and children. I also recommend he find a better spymaster to improve his chances of, er, successfully eliminating any who cross him. Actually owning some territory would help, so he might need to raise up cash to send his army of adventurers somewhere.
The whole point is to get cash by marrying a rich socialite so YOU OFFER NO SOLUTION
I'm also white. I am using a relative who died more than 100 years ago to claim the throne of Sweden, after all.
