SPOILER: In order to warn about this main quest bug I'm going to have to deliver main quest related information. Okay so I discovered Sky Haven on complete accident when i was just farting through the forest and because im proudly a level 100 conjurer I was able to take on the healthy amounts of guards standing outside the thing. I went inside and noticed the first puzzle. I thought wow, this is cool! And proceeded to do the trail and error method of solving the puzzle until I landed on the sequence that was right and i proceeded onward: Note to the reader, this was my big mistake, you aren't supposed to do this puzzle early. Did the second puzzle and then found myself before a big huge face and I couldn't proceed and figured I came here too early and sure enough I was right. Later on I got Esbern and we talked to Delphine and all that jazz and they wanted to meet me at the Sky Haven temple. Cool! I thought, I could just fast travel there. HOLY CRAP, DO NOT DO THIS!!! I fast traveled in there and i appeared before the huge stone face and Delphine shortly ran up next to me but Esbern was nowhere to be found. I went outside to see if he was stuck or if he was eaten by wolves or something when i found the obvious boss battle which was the Elder Dragon. At first I was dissapointed because if i had traveled with Delphine and Esbern, and if i hadn't killed everybody else before-hand, than there would have been a cool-ass huge battle. Oh well, I killed the Elder Dragon and I found Esbern stuck on a plank of wood. After i pushed him around he ran back into the Sky Haven, we met back up with Delphine, did all the circle crap, the door opened and they proceeded to run as fast as they could away from the door. I followed them and they just stopped at the first puzzle. Crap, they were supposed to tell me what to do at the first puzzle. I must have done it too early and messed up the whole continuity and now they have no idea what the hell. I just thought I'd warn you that you might have some problems with that main quest if you do the puzzle too early and find yourself accidentally solving this.
