I've taken it upon myself to destroy all the Thalmor I can find. Problem is, I did so without the guidance of the main quest. Now when I arrive at the embassy for "Diplomatic Immunity", they all attack me on sight. I can't attack because my arms are locked at my sides. Is there somewhere I can pay a fine to get through this mission or is it forever out of my grasp?

Also, there is an Argonian named Deeja in Solitude that attack(ed) me on sight. She was essential so all I could do is constantly beat her down. I ultimately made her nonessential and killed her, which started the "Lights Out" quest. It said to find where Jaree-Ra hid the loot. I ignored it because I figured I broke the quest and went on. I walked into Solitude proper only to be attacked by Jaree-Ra. He was essential too, so I made him killable and killed him, which ended the quest. It's no big deal but still a bit of a puzzler as to why she was hostile with no direct cause on my part (I think).
