I reread the last two Daenerys chapters of A Game of Thrones because of someone's insightful post on another thread (Daenerys Targaryen's Power Plays). The decisions and the events which led to the birth of the dragons are the topic of countless discussions. And well they should be because it is perhaps the most significant event to have taken place in the story. I do not claim to have more answers than I did before my reread. I have more questions. But I picked up on a few details that I missed during my two readings of that book. I will list them here for you.
Miscommunication or deception. Khal Drogo was dying, not dead. Daenerys asked for a cure. Mirri Maz Duur says "only death can pay for life." Mirri wanted to perform necromancy but presented it as treatment to keep Drogo from dying, basically cure him. It is pointless to perform necromancy on the living. I want to be clear on this. Why in hell would Mirri use necromancy as the treatment for a man burning with fever? Miscommunication? I don't buy that. Mirri took advantage of Daenerys's youth and trust. She deceived Dany in order to murder Drogo. Mirri was planning to murder Drogo all along. It was easy. She can easily let his body slip under the water and deprive him of oxygen, which can cause damage to the brain. Drogo's is the death worse than death. His soul is in darkness forever howling. Mirri wanted to punish Drogo, send him to hell.
Daenerys goes through three cycles of sleep+dream+waking. Each time, her fears and her doubts are burned away. The themes of the dreams have fire, tears, water, blood, and always dragons. Fire and water are necessary for the tempering of weapons. Daenerys herself goes through a tempering. She comes through stronger and more sure of herself. The Dragon has awoken.
Daenerys is Azor Ahai and the dragons are her weapons. Lightbringer is not necessarily all weapon though. Lightbringer brings light and chases away the darkness. Darkness is not just the absence of light but means evil. Bringing freedom to slaves and putting a stop to the slave trade is "bringing light and driving away evil." It also means she will be instrumental in rebuilding the world after the long night has passed. To bring light to a darkened world.
The ghost of dead kings in faded clothing are not Targaryen monarchs. I think they are the previous incarnations of Azor Ahai. Why are they cheering her on? Because she can do what they failed to do. End the cycle of the long night for good. She is the first female of their line and the only one who can bring dragons to battle. The best they had were swords of pale fire, which pale in comparison to three dragons.
Mirri tried to poison Daenerys.
Icy breath means death. A death worse than death is what Mirri did to Drogo. Alive yet a prisoner within his own mind. Something similar to complete paralysis. Truly a hell. Daenerys' instinct in her dream told her to fear the darkness. It's obvious to me that Mirri tried to poison Daenerys. Daenerys is resistant to many ailments that would fall an ordinary human. She fought off the poison and recovered.
Alive, but unable to move, speak, or eat is a different brand of death. Take careful note that this is basically what the children of the forest do to the green seers. Attach to the trees where they live in the darkness. Bloodraven tells Bran that dark is good. Bran should not be afraid of the dark.
Mirri is versed in the same parlor tricks as Mellisandre. Knowledge that could have come from Asshai. The shadows in the tents and Rhaego's appearance are illusions. Mirri studied under Marwyn and would have heard of Princess Rhaenyra and the Dance of the Dragons. She would know the lore of the half-dragon baby born to Rhaenyra and chose to use it for her illusion. Rhaego was most probably normal.
The hatching of the dragons is the other sign of Azor Ahai reborn. I am mostly in agreement with the *Son of Man's (Daenerys Targaryens' Power Play) hypothesis for how Daenerys figured out how to hatch her dragons. She figured it out and put all the data together in the last chapter.
Daenerys believes Rhaego died because of exposure to Mirri's blood magic. She believes Ser Jorah took her inside that tent by mistake. She never mentions it back to Jorah and she never held it against him. She has a wonderful capacity for understanding and empathy. I can now fully understand why she was later furious over Jorah's betrayal in Book 3 and banished him.
