The rigging cables that support the mirrors are the only cables not shown here.
Here's a closeup of the mighty anchor of Gaea. All the cables fasten to the hub, holding the body of Gaea
together, resisting the fantastic centripetal forces generated by her nearly once an hour spin rate. The
hub is also the resting place of the great muscle that was used shortly after her birth to pull out and
form the rest of her body. In the model, I've made it 10 km thick. It may need to be thicker, but the 10 km
thickness lets it match to a certain degree the approximate 20 km distance from the Mad Tea Party sited
a couple of times
To get a better idea of the the interior of the hub, the images below show the approximate location of Cirocco and Gaby when they entered the hub in Titan. They couldn't see much because the light level is quite low in the hub. They exited facing a cool breeze from the Oceanus spoke, so due west.
The three pics below show an approximation of the location, on the east side of the Rhea spoke, of the Mad Tea Party.
