(urth) do the Hierogrammates *care* about the megatherians?

What is the basis for saying the flood is universal?  It is not predicted to 
be such in Dr. Talos's play - he says in fact that new continents will rise 
from the sea.  The old Autarch says the Ascians will survive the advent of 
the White Fountain better than the Commonwealth.  And there obviously isn't 
enough water to drown the continents anyway unless they are all flattened 
somehow to the same altitude.

I think there must be.

Either way, it doesn't really make much sense in terms of known physics. 
Gravitational radiation is not strong, and there is no obvious source of it 
except from the centre of the Sun, where perhaps the black and white holes 
will orbit each other for a time before merging.  But the frequency will be 
high and will couple poorly to geophysical systems, even if it would be 
strong enough.  (Gravitational radiation is so weak that nobody has managed 
to detect it directly from any source yet, although there is indirect 
evidence for it in certain pulsars.)

Of course, we don't know how the White Fountain was transported, and we must 
assume it was slowed down within the solar system, and maybe whatever means 
accomplished this created gravitational radiation or some other effect which 
disrupted Urth.
