Very haunting, disquieting module, I like it very much. Alzabo is horrible, love him.
Some of the links between places are a bit confusing - 2. leads to "the island at 6" but 6 is described as a cave rather than an island - and I was a bit thrown by the statement that the route between 4 and 5 is barred, as there isn't an alternative that connects 3 and 4 to the other areas (except leaving and using the other entrance) - does this just mean some effort is required to traverse it, rather than it being completely insurmountable?
