So, it looks like I found another distraction amidst my attempt to actually finish my long-term project.
There's
this guy, a Dutch politician and commander, and an acquaintance of Napoleon. He's not that famous internationally, but he's described as a complete monster in my country's history books. His greatest feat is building a massive road connecting the east and west coasts of Java, which he completed in just a year. The road greatly boosted commerce, economy, and strengthened the occupation of Dutch forces in 18th-19th century Dutch East Indies/Indonesia.
The less-than-stellar part, however... no road that long could naturally be completed in just a year. He enforced a strict forced labor policy that claimed the lives of thousands, and even now, there are ghost stories/urban legends on how people travelling the road could see apparitions or hear voices of these countless dead workers.
In my mind, he'd be an evil, hate-sink Rider similar to Columbus, though I still have no idea on what his NP could do. It would obviously be based on the road, and the concept of "connecting two places together at the cost of countless lives". Maybe a teleportation gate that siphons massive amounts of mana from his surroundings? There could also be a demerit where spamming the NP could alert the vengeful spirits, and if they're pissed enough, they'd drag him kicking and screaming to the shadow realm.
Anyway, just thought I'd throw this out here. I may or may not get to him myself eventually, but I don't have any idea on how to develop his character beyond the classic corrupt, money-grubbing, attention-seeking, "Napoleon-senpai notice me plz" slaver, not to mention I already have a ton of other unfinished projects.
