This script was used for texts in languages in the Reatic language family (Paralian, Wentican, and Nevalian) throughout the Middle Ages, until it was replaced by the current Estrellian script in the 1800s. The only phoneme without a letter was /x/, represented by <kh>. <ph> was used for /φ/ in Paralian only, being the only Reatic language with that phoneme. Solakinese still uses a variant of this script.
so yeah i’m moving conlang stuff onto this account
