Leviathan is really just akin to "Large sea monster", similar to "Kraken" and the likes.
But for other "Demon" and "Devil" names, there's a few adjectives out there:
Dare Devil Dive (though more conjuring of stunts)
I'm sure there's a longform CF article in various culture's comforts in conjuring/naming with pagan and other religious contexts. Here in America, there's an arguable "PC" vibe of leaving religion out of the naming, to @solarfall's point of playing to cryptid and local legend instead.
Lol I think we need some investors to join this thread. It doesn't have to be the Bible just Moses. That way we could attract both Christians and jews to Moses Land. Does anybody else have any other Moses themed ride ideas xD
I have another one
THE COASTER OF BABBLE. All the ride ops speak different languages so nobody knows what the hell is going on. Best part is any coaster could be converted to the coaster of babble just change out the ride ops and BAM no more trains will ever leave the station xD
