At five-four, Keliatharas is unusually tall for his kind but with the unmistakable slender build.  He boasts the ageless beauty of the Silvanesti, with high cheekbones and sharp angles made lean instead of gaunt.  His pale flesh hints at a silvery gleam, possibly as some result of channeling the silver moon or as a minor after effect of the Test.  Braids in varying sizes contain what would otherwise be a cascade of amber reaching Keliatharas's navel, now neatly prevented from blocking his eyes or boyish face, and adorned with runed hair beads of silver and ivory.  Ink stains constantly color the tips of Keliatharas's left set of fingers, though more as smudges from following along the page than the fresh droplets of an active scribe.

While Keliatharas's simple staff hints at his arcane talents, he tends to wear proper wizardly vestments only for ceremonial purposes.  At other times, he goes with a more practical boots, breeches, and tunic of bright hues and fine weave if not fur and leather.  When possible, Keliatharas wears a long leather overcoat and felted cloak, each dyed white and lined with cloth of silver embellishment and visually reminiscent of the robes of his order.

Following his Test, Keliatharas's eyes were transformed into clouds over a black sky.  Whether the clouds shift or not is impossible to spot, with the constant storm of lightning illuminating the various depths of Keliatharas's eyes.  His voice sounds ghostly and ethereal.  The unique features of his voice make any disguise where Keliatharas has to speak unfeasible. While speaking in the common tongue, Keliatharas's liquid pronunciation tends to add unusual accent points and enunciate words with to the fullest syllabic potential.  He has a competent enough command of the language, but the thickness of his accent would indicate that he only learned it recently.
