Is there a "fast travel" feature in the Witcher (enhanced edition)? I could not find any by clicking on the map, but it would be really useful sometimes.
Yes, there is some sort of although heavily limited. Without spoilering: At least for some time you can use Places of Power to get back to a house in the city. Furthermore you can later use several teleporter places throughout the world although you can only travel from one teleporter to the other.
