Senrian archipelago

The Senrian archipelago (Senrian: 썬류우렅또우, Senryuu-rettou, Gyoumon: 千竜列島; Isotaman: シンルーヌシマ, Shinruu-nushima; Esamankur: シㇴルィモシㇼ, Sinruy mosir; Cotratic: Sanlux malꜧuř) is a stratovolcanic archipelago consisting of more than 12,000 islands located off the southwestern coast of Coius, bordered by the Lumine Ocean to the west and north, the Bay of Bashurat to the northeast, the Rangyoku Strait to the east, and the Honghai Sea to the south and southeast. The archipelago spans roughly 2,554 kilometers (1,587 miles) from east to west, but is only about 460 kilometers (285 miles) wide from north to south at its widest point.

The main portion of the Republic of Senria spans the entirety of the archipelago. [politics and contemporary stuff]

Etymology and terminology

[senrian senryuu-rettou and isotaman shinruu-nushima, both 千竜列島, both backformations from senryuukoku and therefore have the same etymology about pairyuu and toyomike and whatnot as "senria"] [the senrian government has also established official names in esamankur, sinruy mosir, and cotratic, sanlux malꜧuř, which also literally just mean "Senrian archipelago"]

[esamankur has two indigenous names for the archipelago, porohumbe mosir ("great whale land") and tannekamuy mosir ("snake - lit. long god - land"). the former is pretty well-established as emerging from creation myth, in which a wagtail called a great whale to the surface of the ocean to form the archipelago. the latter is contentious because of debates about when it emerged and what it's meant to mean - did it emerge comparatively late, an esamankur effort to calque the name "senria" and the idea of a dragon into their language predating the 1900s imposition of sinruy? or did it emerge much earlier, predating the arrival of proto-senrians in the archipelago entirely, suggesting that senria's mythic origins are in fact something they took from the esamankur? or is it simply comparing the long and narrow archipelago to a serpent?]

[the traditional nivkh name was the rather uninspiring aꜧř uř, literally just "the nearby islands"]

[poetically sometimes "the land of the setting sun" in both senrian and foreign-language texts]

[terminology - sometimes called "mainland senria" or "senria proper" to distinguish it from the Sunahama Islands and any other outlying bits of rock senria claims]

Geography

[four "main islands" - from largest to smallest, kousuu, tousuu, yuusuu, gyousuu]

[three larger "small islands" which lie off of the main islands (primarily kousuu, but rousima's kinda also off of yuusuu) - kisima, kanasima, rousima]

[yet smaller outlying "small islands" - sugisima, kaedezima, that one between kousuu and tousuu i've yet to name, a great many others ICly]

[isotamas - narazima and the near isotamas, iezima kumezima and the far isotamas]

[hibotus -yorosima kurosima etc]
