resonantseid
Resonantseid is a fictional or speculative concept describing the amplification of seid energy through resonance with environmental or sigil-based frequencies. In many settings, seid (or seiðr) is a form of Norse magic practiced through ritual action, chant, and rune-like symbols. Resonantseid posits that when seid energy is tuned to a specific resonance—whether acoustic, magnetic, geological, or geometric—the efficiency and reach of magical effects increase.
Origin and use: The term appears in fantasy literature, role-playing systems, and esoteric fiction as a model
Mechanism: The proposed mechanism is constructive interference between the practitioner's energy field and an ambient resonator.
Measurement and evidence: In-universe instruments—spectral analyzers, resonance meters, and sigil-mapping charts—are used to identify and verify
Applications and variations: In fiction, resonantseid can enhance divination, warding, or spell transference. Some traditions differentiate
