It is recommended you leave as much space as possible in the middle of the play area when completing a delve. A delve can take up considerable table space. If you run out of room on the table during a delve, you can do one of the following:
• Shift all currently revealed tiles to make room for the next tile, keeping the tiles connected in their current configuration. This works best toward the end of a delve, when few tiles still need to be connected.
• Place the revealed tile on another part of the table with more space; then mark the connected hexes on it and the explored tile with unused overland tokens. This requires careful reading of the map, and works best if only one area of tiles is marked this way.
