Vaelinthar appears as a shifting form of molten glass and iridescent smoke, their silhouette constantly wavering between solid and vaporous states. Their movements flow with jagged bursts of energy—like flickering embers expelling occasional sparks—and yet when still, they hold an uncanny serenity as if carved from frozen time itself. Their core pulses softly, a liquid flame trapped beneath a crystalline shell, occasionally resonating a deep humming tone. Paradoxically, despite their volatile elemental nature, their voice carries the soothing cadence of a lullaby, unsettling listeners by the sharp contrast. Around their neck floats a shattered obsidian circlet, cracked but radiating faint protective wards.
