Vianic

Vianic (Vianic: Vian-i ski) is a constructed language created by Akrivus and spoken by the Vianic people and their representations in numerous fandoms. While it adheres to the Sonic fandom, there are actually multiple, subtly different, constructions of Vianic used in different series, fandoms, and stories.

The Vianic Alphabet (Vianic: Vian-i acba) is an alphabet created specifically for the Vian language. It takes a lot from the Latin alphabet while simultaneously being different from it by changing the sound of letters.
