Hollow Armor

Hollow Armor begins as Eithan’s signature Enforcer technique in Blackflame, a subtle, pure-madra lattice that spins through body and spirit to blunt incoming strikes. Over subsequent volumes the technique is refined and expanded, its shimmering distortion becoming more pronounced as Eithan layers additional principles—such as the Hollow King’s Mantle—onto the original construct, turning a personal defense into a battlefield-scale aegis. By the later books the armor evolves from a purely protective measure into a versatile platform that can channel offensive madra, absorb hostile techniques, and even project counter-strikes, reflecting Eithan’s own ascent from Underlord to Monarch-tier combatant.
