The Luziyca-Namor border, known also as the Namo-Luziycan border (Luziycan: Granitsa mezhdu Namor y Luziyca, Internacionala Granitsa, or Granitsa i Namor y Luziyca, Namorese: Намора-Лузейика бенчин), is the longest international border in Esquarium. It is entirely a terrestrial boundary, running from the convergence point of the Luziyca-Namor, Geadland-Namor and Geadland-Luziyca borders in the north to the convergence point of the Luziyca-Namor, Katranjiev-Namor and Luziyca-Katranjiev borders in the south.
Most of the border is defined and recognized by Namor and Luziyca, although there is a dispute over the exact location of the border in the Nantai area (Namor considers the boundary between Nantai and the Luziycan states of Lazar and Evpraksiya as part of the international border). Up until the construction of the Namo-Luziycan barrier in the late 1990s and early 2000s, the border was demarcated by man-made or natural objects, such as fences or trees. Inability to recognize where the border exactly laid led to periodic clashes, with a significant example being the Vulan Incident. Nowadays, a series of walls known as the Namo-Luziycan barrier was designed to prevent illegal movement across the border.
In both countries, a significant portion of the armed forces is reserved for the protection of border areas, effectively making the Namo-Luziycan border among the most heavily defended international borders within Esquarium.
Despite its length, the Namo-Luziycan border does not enjoy as many travelers as do other borders, primarily due to the historic relations between Namor and Luziyca. Currently, there are four border crossings, known by both countries as "port of entries (Ручин Коан in Namorese and Pereschaniye i Zapis in Luziycan)." Listed from the northernmost to the southernmost, they are:
- Jikfan Port of Entry (Jung To Port of Entry on the Luziycan side) - Sosnagrad, Upper York and Jikfan, Txotai
- Central Avenue Port of Entry - West Po'ai, Republic of Nantai and East Po'ai, Nantai Prefecture, West Namor
- Lana-Suchun Port of Entry - Lana, Pustinia and Suchun, West Namor
- Detente Port of Entry - Kirishi, Voshkod and Kunsu, Xhipei
Vulan Triangle and Cimmaron County
There was a territorial dispute over the area which is known to Namor as the "Vulan Triangle" and to the Luziycans as "Cimmaron County."
The Triangle was a triangular-shaped territory that was controlled by Antelopian Namor until it fell to Luziycan control in the First Namo-Luziycan War. Most parts of the territory were formally annexed into Luziyca as Cimmaron County of the state of Pustinia. In spite of this, a few places, such as the village of Vulan, remained under Namorese control (especially in terms of civil administration). In 1958, as part of its campaign against East Luziyca-backed Republican loyalists in West Namor, Liberationist Namor seized control of the entire area and expelled all Luziycan inhabitants. East Luziyca continued to regard Cimmaron County as part of its territory until after reunification in 1991, when the claim was dropped. Vulan and surrounding areas are recognized by both Namor and Luziyca as within Namorese territory, and no dispute over that area currently exists.
- Main article: International position on the Nantai dispute
Because of the dispute over Nantai, the exact location of the Namo-Luziycan border around that area is a matter of contention. Namor, which claims Nantai as Namorese territory, considers the border between Nantai and the Luziycan states of Lazar and Evpraksiya to be part of the Namo-Luziycan border. Likewise, the border that currently runs between Luziycan-controlled Nantai and Namorese-controlled West Namor (the one that divides the city of Po'ai) is temporary and will last until such time that Namorese sovereignty is restored over the region. The Namorese side does a lot to emphasize this claim - Namorese maps, when drawing the Namo-Luziycan border, draw it as being located west of Nantai. Many of these maps do not show the de facto border at all to imply that there is no dispute, although some might feature a dotted or dashed line to represent the actual extent of Namor's control.
Luziyca does not recognize the Namorese claim and considers the border between Nantai and West Namor to be part of the Namo-Luziycan border. Luziycan maps generally show Nantai as being part of Luziyca, and rarely if ever even show it as "disputed territory." Luziycan maps showing Nantai as Namorese are virtually non-existent.
