Locations have Life Points, produce resources, have space for your troops and some of them may provide special powers.
Having decided what faction to play it is time to choose your stronghold. A specific type of Location is called a Homeland. Unlike other Locations, Homelands require no casting cost and cannot be played during a game. It will be put on the table before playing and it will determine what resources you produce throughout the game. The Homeland is kept separate from your Stack and Resources.
A Location is like a Homeland except you can play it during a game and it has a casting cost, meaning you will have to spend resources to build the Location. You can also play Creature cards on Locations.
