Strait of Abren
The Strait of Abren is a critical junction that links the Hesperic Ocean with the Asperic Ocean. The strait, located within the country of Dematisna, divides the continents of Uletha in the north and Tarephia in the south near 29° North. As with the Strait of Lyc, the Abren is an important sea route for ships traveling between western Uletha and Tarephia and the Asperic Ocean via the Sea of Uthyra.
At its narrowest point, the Strait of Abren is just 5.3 km (3.3 mi) wide. The thoroughfare is about 70 km (43 mi) long. While there have been multiple proposals for rail or road crossings over the years, bridges and tunnels have always proven cost-prohibitive due to the strait's depth. A cargo ferry is currently the main point of crossing for vehicular traffic.
At the northern entrance to the strait is the Zona Internacional Abrenica (Ingerish: Abrenic International Zone; Franquese: Zone Internationale Abreniq; Mazanic: منطقة أبرينيك الدولية), an international territory controlled by the Assembly of Nations Peacekeeping Forces. The southern part of the strait is home to two major cities, which together form a metropolitan area of over 15 million people.
The northern part of the Strait of Abren roughly resembles the letter "Z", making it a challenging passage. Therefore it is obligatory that a pilot escorts the greater ships. This bottleneck has made the strait an important site of commercial and cultural exchange (and conflict) for millennia.
