Sithigh Don't worry you can't enter the pyramid temple again. It just goes to the Mirror Pyramid mine. That's the only crystal I did get.
Please also note that some time could be saved by just investigating Gamemaster's posts (way above).
I don't understand why my gold quest frame disappeared and the game failed to show I needed to go to "the City of Gods on the MAIN map" in the previous region where my quest was disconnected. It got me lost because I couldn't be there for a few days or see it. But after I talked to the person hiding there it the frame came back again.
It would improve the game to add another gold framed hint to continue the questline and help keep the players from getting lost here when it goes dark.
