Sego Writer

In the late 11th century AE, Aaarician explorers travelled down to Sego. Though Sego was never conquered militarily by the Aaarik Empire, cultural diffusion did occur, including the spread of the Cirogese Script, also called Cold Water Fish Script. 

However, adapting the Cirogese script to Sego’s language posed several challenges. Cirogese has a phonology that is drastically different from Sego’s: it lacks fricatives, has fewer vowels, and has a far simpler tonal system. Additionally, Cirogese has no labial phonemes, which are prominent in Sego. These differences led to the development of numerous workarounds to transcribe Sego words into Cirogese.

In response to these issues, a scholar on Sego’s Guava Islands decided that the best solution was to abandon the original Cirogese script entirely, save for its aesthetic qualities, and create a new script specifically designed for the Sego language. Support for Sego’s phonetic inventory was done with new animal glyphs, which were also chosen to highlight species native to Sego’s waters, like marlin, flounder, and sea turtles.

This retooled script was originally published in 1034 AE. It is now the most common script used for writing the Segoan language (although in some regions, the Nuejan tallymark script or the Sea Nomad runes are used instead).
