The coast is formed by the Arinian Sea on the southeast and the Gulf of Isalno on the northeast. The Qosk and Hekori exclaves are surrounded by the Liara Pentarchy on their land borders, with the Strait of Ukasa and Gulf of Isalno forming Hekori's coastal boundaries. It is the most populous Rits-majority country.
