Nidurrâb is a widely spoken language. It is an alien tongue, brought to Bal-Kriav by the Lith-Crillion. Other races of the realm that have adopted Nidurrâb as their primary language are the Khazarkars, the Nithians, the minotaurs, and the Sadar-Nizar.
The Khazarkars mastered Nidurrâb from the ancient relic Agêrdul. Over time, this device facilitated the Khazarkars' abandonment of their own language in favor of adopting the Lith-Crillion's speech, Nidurrâb.
During their enslavement under the First Khazarkar Empire, minotaurs were compelled to learn and utilize their overlords' native language. After numerous generations, the minotaurs had relinquished their ancestral Primordial tongue.
The Sig-Lorm also converse in this tongue. They acquired it from their period collaborating alongside Ptah, during the construction of the labyrinth Reconstruction, and their education in the Way of the Mind.
The Langurâpha language is derived from Nidurrâb.
