Hellean is a regional language spoken primarily by the population of the Hellean peninsula. Rather unusually, Hellean is a semi-standardized language, having been intentionally developed to ease communication across speakers of the widely varying old Hellean dialects. Developed by a group of scholars and linguists, standard Hellean has no official backing but has nonetheless been widely adopted due to its use in intellectual and diplomatic circles trickling out to the broader population.
Older Hellean dialects still survive, but generally in a marginal form. For example, on some islands within the Sea of Ersas the old dialect of Ersas Hellean remains in use. The Ersas City States are home to the largest concentrations of speakers of this dialect, though their numbers are rapidly decreasing as the standard dialect is adopted more broadly.
