The HOTU seems focused on dragons, fire, and magic. They show visions of the political climate of Westeros, but mostly about how messed up it is at this point—hence the necessity of a savior. The IT itself doesn’t seem to concern them. Why would Dany need to slay the lies of the well-meaning Stannis, Aegon (I assume) and Jon? They’ll be competing for resources. The kingdom will be irreconcilably split following the savior of their choice rather than pooling everything under a single savior.
