Yep, good thought. I was thinking of how telling truth has risk as well so there's a tradeoff, but in this case the brutal truth actually genuinely is pretty off putting anyway. The whole super war and reason it was banned in the first place is because they did genuinely go wrong, every single time. Nobody figured out how to constrain the hypergates to keep Demons from coming through, and/or the hypermagic was always horribly misused in the end. If it had all worked, the entire existing era would be different. But it didn't. Why not just tell people that?
It's extra odd now that I think about it because people DO know about hypermagic and do indeed have a massively strong aversion to it as "The Dark Arts" and "no good can come of it in the end". They just don't know the source, which leads to those who are strong, educated and intelligent but don't know they are missing key pieces like Marcille to see the obvious holes of>"well this stuff is clearly dangerous but if I'm good enough I can use it for good just like all sorts of other dangerous power, not like the power actually has a mind of its own haha"
except the power really does effectively have a mind of its own. Or at least is tied to one at the core source of it. Seems like the elves should already be 95% of the way there to>"dungeons are concentrations of Dark Magic that frequently host demonic creatures at the core which seek to mentally corrupt and twist rather then physically attack"
which would sure as fuck change a lot of the way people see dungeons. The elves/dwarves can from there just institute some level of win/win, "we will pay lots of money for info on dungeons and share the loot from shutting them down". Right now instead everyone has incentive to hide them.
