The language known as I Kronurum (IK) is a part of the Northern Languages linguistic family, which populates the northern region of the central continent.

Notwithstanding the several subgroups that have split from this branch at different stages, this Central Branch of the family has been studied as a continuity in which four main stages can be identified: Ancient IK (AIK), Old IK (OIK), Middle IK (MIK; together with Early-MIK, EMIK) and Modern IK (MoIK; together with Early-MoIK, EMoIK).
