A song of Ice and fire discussion (spoilers incl A Dance with Dragons)

['thul]

There is another potential dragon, buried at summerhall. Its egg belonged to Aegon V, who died trying to hatch it.

The time passed between last two books is zero to some, since good part of ADWD occurs same time as AFFC.

It does seem like a competition in the red priesthood to find that Azor Ahai.
As for the lack of land bridge, that is irrelevant. Ever heard of the Fimbulwinter?
That is 4 entire years of unceasing winter. The oceans freeze enough that anyone can walk across them. A similar thing is being built up to in ASOIAF. It has been the longest summer on record, and when summer is long, the following winter is equally long.
If you then bring in the fact that ASOIAF seasons last years to begin with, you'll get a winter long enough for children to grow up never knowing anything but winter.
