Slyver

Slyver is Eren Long's proud Silver Dragon Curse and lifelong companion, not a hostile entity seeking control of its host.

Biography

The Nest and the Supreme Human Alliance

Slyver accompanies Eren's assault on Supreme Human Alliance targets, mocking his rust while warning him about Blood Incursion and Primordial techniques. A Vylraen Seal fueled by murdered children severs their connection and exiles Slyver to an unknown realm for a subjectively immense time. When the seal weakens, Slyver returns enraged, manifests through Silver Domain, and burns Eren's attacking brothers. (Chapters 821, 825, 828)

Draconic form and personality

Slyver manifests as a majestic Silver Dragon surrounded by streams and rivers of silver energy. His exact size, eyes, and physical permanence outside Curse manifestation are not established. He is proud, sarcastic, impatient, protective, and deeply compatible with Eren; exile terrifies him despite his status as a mythical monarch. (Chapters 821–828)

Silver Dragon Curse powers

Slyver grants pseudo Curse Transformation, producing dragon wings, enhanced eyes, curse power, and silver energy constructs. Within Silver Domain, Eren can manifest Slyver's halo and full dragon image, whose breath burns lifeforce. A sufficiently powered Vylraen Seal can remove Eren's curse force and temporarily sever Slyver entirely. (Chapters 821–828)

Relationships

Eren Long is Slyver's host, closest companion, and perfectly compatible partner. Slyver saves Eren from depression, helps him escape his family, and obeys even momentary wishes to spare his brothers. Eren's family views the Curse as something requiring exorcism, while Eren considers Slyver the best event in his life. (Chapters 826–828)

Items

Slyver uses no conventional item. The Vylraen Seal is an enemy restraint powered by victims' blood, while Eren's longsword and transport equipment belong to Eren. (Chapters 824–828)
