Vezhár appears as a tall, lean fey with the stillness of a heron waiting in reeds. His skin has the matte, finely ridged texture of pale birch bark, interrupted by delicate green lines that shift like reflections on water. His dark hair hangs in narrow, damp-looking locks, each threaded with a single seed or sliver of leaf. He moves without seeming to cross the space between one place and another; people often realize he is beside them only when the air cools. Before speaking, he draws one careful breath through his teeth, then waits just long enough for others to wonder whether he has changed his mind. He wears a tiny, plainly made wooden whistle on a cord, a strangely domestic keepsake for a figure of such ancient power.

Vezhár is patient enough to let a dream unfold without interruption, yet impatient with anyone who treats a promise as a suggestion. He is compassionate toward frightened people and merciless toward those he believes exploit them. In calm moments he is precise and almost practical; when his brother is mentioned, grief makes him speak in clipped fragments and choose dangerous plans too quickly. He wants to be trusted, but keeps information back because he fears that the truth will make others abandon the task.

Vezhár and his twin brother were remembered in old fey accounts as guardians of the forest's border, though neither cared for titles. When an orc raiding party threatened Queen Yolande as a child, his brother held the attackers off while Vezhár spirited the child to safety. Vezhár still remembers the child's muddy shoes and the promise he made to bring her back to her family. Years later, the twins were separated. His brother was captured, tortured with cold iron, and twisted into the Werewolf Lord. Vezhár escaped, but has never forgiven himself for leaving his twin behind. The corruption spreading through the Suss Forest and the open Khesarah Kudlolee gate have made that old failure urgent again. He believes destroying his brother may be the surest way to close the gate, but cannot admit that he is still searching for another answer. He granted Gargas Ezroark healing and warlock power in exchange for allegiance, and now reaches him through dreams with warnings about Gurthel-thalanee, Leeh Hollow, and the dangers ahead. He has also directed Gargas to arrange a year-long service between Wilborin Barvalor and Tor Edvard. Each warning costs Vezhár a little of his ability to distinguish his own memories from dreams, and he is increasingly afraid that he will one day mistake his brother's voice for his own.
