(I like this idea, so I'm going to keep the ball rolling.)
Most of this water is collected either at the cables' many anchor
points as it
slowly trickles down them from the icicle above, or at the Tower On
The Hill
which sits directly beneath Dredungadrip's largest point. As the
single largest
and most reliable source of water on Twirlip, this drip site has seen
much
construction, which eventually culminated in the tower. From a
distance it
resembles a giant candelabra; with the recent addition of the seventh
arm, it
now collects nearly half of the water which falls on the centre of the
world,
with most of the remaining drip sites being too unpredictable in
location for
permanent structures.
This local concentration of usable water has led to the Tower On The
Hill's rise
as a centre of commerce and industry, as well as, some would argue,
blatant
corruption.
