Morgul-sheen

Morgul-sheen, the eerie pale corpse-light emanating from the Witch-king's Morgul-blade, first manifests in The Two Towers as a decaying exhalation that illuminates nothing yet casts a green-white reflection in the eyes of those it ensnares, evoking dread and otherworldly menace. Though appearing only in this single book, its brooding fade into shade underscores the insidious, lingering corruption of Mordor's dark sorcery, a harbinger of the spiritual decay threatening the free peoples of Middle-earth. Across the series, it symbolizes the Witch-king's lethal power, tying into the broader narrative of shadow and domination without further evolution in later volumes.
