This is the battle screen at the start of a battle. You can hold and drag the right mouse button to move the battle field map. Use the mouse scroll wheel or the arrow keys to zoom in and out. Right now you can only see part of the map.

Flux Wells Controlled: This shows how many Flux Wells each player controls. This is the begining of the battle so there are no wells controlled.

You & Enemy: See the Player Status page for more details about this.

Your Cards: These are the cards that you have available to play. You wont always be able to play these cards since you wont always have enough Flux or the proper Domain Level.
