Hub

The Hub is the central complex of a basha. It contains all the most vital facilities and controls, and is usually also the oldest part of the basha, with the root system cooling the reactor and the reactor itself maybe hundreds of years old. The kilometre-high needle is an orientation mark for bashindas.

Architecture
At it's lowest level, the Hub comprises the Helium 3 reactor in its thick net of water-roots. Above the reactor lie the watery caves which form the lowest level of the baths Around the baths and the roots are the core complexes of the crackerbox and its storage matrices. The baths spread out a bit, forming the 'spindle' of the Hub, and there are crystal tunnels over the baths for adults wishing to cross into the hub. The Hub is offlimits for children. Elevators around the sides of the Hub give access to the trigam bays in the lower levels.

The cyrstal tunnels lead one to the karma spreads, rooms where gigantic screens show the status of all the processes of the basha. This feed can be mirrored in any bubble. The karma rooms are often deserted, but sometimes siddhas who are stuck on an idea will go there to meditate. Any snatak can enter the hub, but only Siddhas can operate the karma spreads. The elevator shafts curve up over the karma spreads and head up into the needle. The needle is the anchoring mast for fanoses of all kinds.
