Chit never understood why UCirc had so many levels.

He understood the perverse paranoia that had led to its hundred and
fifty expertly concealed exits, and the grandiose architectural style
that left the major corridors large enough for humans to walk in
comfort, and the hastly constructed offshoots on level four where the 
majority of the (at one time rapidly expanding) population lived.

But nothing explained the empty levels between the surface and the
bunnymover terminal, at the bottom. If the warren had had the population
it did today when it was constucted, maybe... but from all reports
there had only been fifty bunnies, and the five hundred squirrels at
the time of the revolution had been the peak.

'Room to expand' was the answer the silver squirrels gave when pressed,
if they didn't scowl and stalk off instead. But you could tell they
were guessing.

'Room to store an eternity of random junk' was Chit's guess. They were
down to level ten with it already, and showed no sign of slowing the
pace. And the scary thing was that Logistics, if asked, could actually
retrieve specific items. Eventually.

Chit was hoping that he and Kara weren't in the files yet.
