Orcish

A derivative of Demonic, Orcish is the simple and brutal language of the most common Shadowborn in Creacia, taught to the Horde Orcs by agents of Lamashtu during the First Ruination. Although it has many dialects--from the Orcfists to the Izerkolith Crests to the Brownbones--most Orc tribes can understand one another (when they are not killing each other in internecine warfare). Like other forms of Demonic, Orcish stays true to its chaotic nature with a malleable syntax allowing for deception and obfuscation.
Lamashtu did not deign, however, to teach the Orcs the Abyssal Script, so overtime, Orc scholars developed their own system of writing called Runic Orc, based loosely off Koraxicon.
