Azkhar stands with the unnerving balance of someone braced against a ship's deck, though the floor is still. His movements are clipped and deliberate; he turns his whole torso to address people, as if refusing to give any one person the advantage of his profile. Within a minute, most visitors notice his eyes repeatedly measuring doorways, ceiling corners, and the empty space between people, never settling on a face for long. His skin has a dry, fine-grained texture like river clay, and his dark hair is combed into narrow ridges that remain precise even after a fight. He smells faintly of hot stone and rain on dust. Unexpectedly, he keeps a little wooden wind-up bird tucked inside his formal sleeve, winding it before difficult negotiations.

Azkhar is rigorous and protective, yet his protectiveness becomes controlling whenever he feels events slipping beyond calculation. In calm company he can be unexpectedly attentive, remembering small details and making himself useful without being asked. Under pressure he becomes brisk, procedural, and dismissive of feelings he cannot quantify. He is not cruel for pleasure, but he can rationalize cruelty as a temporary measure if he believes it will avert a larger disaster.

Azkhar was raised among the surveyors who mapped the unstable caverns beneath the Seventh Nexus. His mother, a patient stone-reader, taught him to recognize the difference between pressure that supports a vault and pressure that cracks it. He learned the lesson, then chose to ignore its moral equivalent. During the Sundering of the East Gallery, an experimental binding collapsed. Azkhar had time to save either his mother or a group of trapped apprentices; he chose the apprentices, believing his mother could escape by the route she had mapped. She did not. The survivors called him brave, and he has spent years trying to make that choice mean something. The Obsidian Tribunal recruited him as a nexus theoretician. He now seeks to bind a lesser deity with the last living shard, convinced that overwhelming magical pressure will force it to select a master and give the Tribunal the leverage to prevent another catastrophe. His former apprentice, Pema, has discovered that the shard responds to trust rather than force and is trying to reach him before the rite begins. Azkhar has not told the Tribunal that the shard's living pulse resembles his mother's old stone-reading signal.
