Using the Grid with a Controller
An organization that has built a Controller can get to the Controller from the Grid and also get into the Grid from the Controller.
Using the Grid to get to a Controller is done in the normal manner - You use a Grid Access terminal and find your Controller inside the Grid.
To get into the Grid from your organization's Controller you need to use a Personal Grid Converter on the Control Tower. It can be bought from Land Control Shops as well as from normal tool shops.
