bio, over the last two years of writing ADWD, GRRM referred to it as "King Kong."
Midna, He is at the height of his popularity, his profession, his ability to generate income, and probably his creative powers. It appears that he's caught in circumstances that are now beyond his control and that he's found it difficult to just say no. Effective?
