Yes, open the magical door

You place the rubies in the eye sockets. As the last one is set all four flare with light and the door opens. You step through and the door slams shut behind you. You had now entered the second half of the dungeon. You recall the goblin telling you that emeralds were now required instead of rubies. Three emeralds if you recalled correctly.

You walk through yet another mist filled hallway. This one felt different however. The hazy details of your memories were slowly beginning to clear. You remembered just a bit more now. You had gotten a step closer to returning to the world you had left and you could feel it.

You continue on through the thick rejuvenating mist and eventually through an opening similar to your initial entrance to the dungeon. As with that time the opening soon seals itself up behind you.
