I'll be honest I wouldn't blame OP for not finding this (I found a species of hister beetle before anything to do with Hitler)

I feel this is a weird spin on the "Clicks to Hitler" game

I was not using Wikipedia to get there. This is something I immediately recognized from research about World War II and possible prophetic fulfillment. I definitely wasn't playing a game when I came across this information either, but I get your drift.

Interestingly, when I searched "hister" on English Wikipedia, I was sent to https://en.wikipedia.org/wiki/Danube#Names_and_etymology

Where it says that “Hister” is a variant of its Latin name.

I think the name is lovely with no reason to change. Surely there are few people who would connect this with silly medieval superstition. Perhaps you can take part in wiping out that association.

User name checks out.
