The Íscégon language, natively céresiú íscégunévu [ˈkeːreʃuː iːsˈkeːguneːʋu], is the main Classical language in the Western civilizations of Calémere. First spoken in central Évandor, in present-day Northern Ceria, where it developed from Proto-Common Evandorian, it was the language spread across most of the continent by the ancient Íscégon Empire; for a long time after imperial times it still was the main language of culture of the whole continent and nowadays it still has - along with Old Nivarese, the language of ancient Nivaren - an important role in learned terminology in all Evandorian civilizations and, through influence of Cerian, a descendant of Íscégon which has become through colonization the lingua franca in most of Calémere, in most languages of the planet.
