Speaking of the Breaking, how did Dragonmount survive all that rearrangement of geography?
Well, the Breaking had different effects in different areas. Some areas were raised up, others lowered, others moved around… but the effects were relatively mild in some areas; Dragonmount was one of them.
Note that Shayol Ghul used to be a subtropical island. The Tar Valon area was moved, but as an entire piece, so the mountain, the island, and the river stayed in the same places relative to each other.
[Which I suppose makes sense, since nobody lived in the area (of Dragonmount), the men would likely have been elsewhere.]
