The Ferry Landing allows heroes to travel between the cities of Mayhew and Lormidia. For a fee of 15 gold, required for each trip, Arex the ferryman will transport a hero across the river that separates the two cities.
Travelling to or from Mayhew will require one turn, while traveling to or from Lormidia requires none. In addition, passage across the river doesn't require any turns.
If travelled from the Lormidia side of the river, Arex will dispel the Invisibility enchantment (Spell 67) found in the Royal Gardens and other enchanted areas. It may take 1 turn to get from Mayhew to Lormidia, but you can circumvent that the other way around by using the Sorecor's Abode, altough it is somewhat more expensive.
