Younger twin brother of Uryzmæg; father of Batraz the steel-hero. Quartigod by registry math. The tragic-conception narrative — Bytsenon killed before Batraz's birth, Khæmyts carrying the foetus as a tumor in his back until the steel-formed Batraz emerges — is among the most distinctive Nart episodes and is structurally connected to the steel-imagery that defines Batraz's heroic identity. The Bytsenon-marriage to a non-human cosmic woman parallels heroic-mating-with-otherworldly-figure motifs across the Caucasian and broader Indo-European mythological frame, and is treated in the registry as mortal-class (the Bytsentæ as a distinct race rather than spirit-class) per the strict-pass criterion. In some recensions Khæmyts is killed by his own son Batraz in revenge for Bytsenon's death; in others he dies with the Narts in the final-age destruction.
