Yes, when it was initially released it was a single gem unless my memory fails me, it was changed very soon after the area was announced.
I could be wrong as initially I got a text saying it required a limited gem rather than the pop-up that shows the current requirement.
Regardless if it was lower or not, it's still a ridiculous requirement that seems to show a bias on morality in the game.
Just because something is outside of the "Good" morality box, doesn't mean we should be shunning it out of character and making ridiculous requirements for against the grain characters. I feel an out of character bias against anything that's not "good" aligned has a detrimental effect overall.
Edit: Another idea is, if the requirement is to be so high then why not make it worth it and put a depot and 2 crafting stations up there?
