This page is an attempt at more clearly defining the different connections between the Watersphere and other components. By doing this we may be able to make more sense out of the complexities.
 Connection 1 - Top half of the Watersphere to the bottom of Sphere 2
 Connection 2 - Bottom half of the Watersphere to the bottom of Sphere 3
 Connection 3 - Very bottom of the Watersphere to the bottom of Sphere Z
 Connection 4 - Magnetic Ring 3 and the Electrical Structures
See the Lower Watersphere Interaction for more information on this connection.
