I don't know any way to unlock the areas, but I want to ask that is there anything after I give the acid to Lyx? The lead mentions a plan, but I can't find the button to proceed.

i think its not yet implemented in the current version of the game happened to me as well

Right as I completed all other quests, a note showed up that said the Crystal Dhena quest had yet to be implemented.   Prior to that it looked like I'd be able to complete it.   So, that's probably what's going on.
