Lake Map
UnderworldRoot
On the Lake map the lake connects coastal clearings like a river and divides forests; a clearing touching the lake is coastal unless a forest separates it. The Ferry starts in the corner clearing that is also coastal. Once per turn, when moving from the Ferry's clearing, a player may move to another coastal clearing ignoring paths, taking the Ferry along, and draws a card. You must still rule the clearing you leave or enter, even with Swimmers, and each player whose pieces ride the Ferry draws a card.
