Explored Tokens are placed certain Map spaces to mark that the location has been explored.
Map Tile
Map Tiles make up the world map on the Game Board. Each Map Tile has six hex spaces on it, which each be Calm Sea, Rough Sea, Shipwreck, Enemy Ship Spawn, (Altar island, Unexplored island, Port island (marked by a banner with the Port's name).
Some game effects distinguish between sea spaces and land spaces; the Calm Sea, Rough Sea, Shipwreck and Enemy Spawn spaces count as sea spaces, and the others are land spaces. Note: when a Storm covers one or more spaces on the map, those spaces count as Storm spaces, which are a special kind of sea space, instead of what they were before they were covered by the Storm. If the Storm moves away, the spaces function as before again.
When the first player takes the first turn of the game, one Map Tile is placed for free. After that, Navigation Orders must be used to discover new Map Tiles.
The Map Tiles are grouped into three groups based on what Act they belong to. As part of the game setup, the Map Tiles are sorted into these groups, each group is shuffled, and then the tiles are places so the Act III tiles are on the bottom of the stack, the Act II in the middle, and the Act I tiles on top.
