Dowsing Orb

The dowsing orb is the primary tool in Demesne and has many uses:
 * When outside a demesne the blue circle will point to the closest demesne.
 * When inside a demesne the blue circle will occupy the center and the player may right click in the air to be told how powerful the demesne is.
 * When the player is occupying one of the 4 center squares of the demesne (where an altar can be built) the blue circle will expand.
 * Right clicking with the orb will complete certain temple marble structures such as the Altar, and Totem Supports.
 * Right clicking on the Altar followed by a machine will link the two, allowing your demesne to power that machine.
