Mulstabhin Passage

The Mulstabhin Passage is the only means for ships to pass between the Great Ocean Ûthaf and the Gulf of Akados and Sinnar Ocean beyond. At low tide, the water drains away leaving a vast saltmarsh surrounding Krivcycek Island. But at high tide the waters of the Great Ocean Ûthaf and the Sinnar Ocean rush in and mingle to turn it into a true island and create the legendary Mulstabhin Passage between those two oceans.
Even at such high tides, the ways are treacherous for any other than flat-bottomed boats, and vessels frequently find themselves grounded on mud bars. For this reason, the Mulstabhins have marked passages with withies — long, flexible willow rods — for generations. These long rods are stuck upright in the mud on either side of the deeper-water channels, and when high tide comes, the tops of the rods remain visible above the surface of the water. These serve as guides so that ships can pass between them and avoid grounding themselves in the shallows. A whole series of these withy channels extend between the island and isthmus, and between the oceans to the north and south.
