Vaxlar stands tall with the characteristic lean, corded build of the Githyanki, though his posture is slightly slumped from decades over scrolls. His skin is a dusty, pale olive tone, etched with fine, silver ritual tattoos that glow when he casts. He wears a breastplate of ancient Gith design, intricately embossed with celestial maps, over layers of indigo and charcoal silks. His eyes are small, sharp, and obsidian, usually hidden behind a pair of heavy, bronze-rimmed spectacles that he constantly adjusts.

He is intensely analytical and speaks with a precision that many find grating. Vaxlar does not just view magic as a tool, but as a language that the rest of the world is consistently misspelling. He treats every interaction as a peer-review session, often critiquing the grammar or logic of those around him. Despite his aloof nature, there is a deep, desperate pride in him, a need to prove that his lineage of 'Sages of the Silver Void' is not just a myth.

Vaxlar is a scion of the d'Gish dynasty, once the preeminent architects of the Githyanki's most secret floating citadels in the Astral Sea. Centuries ago, his family's library was purged by the Lich-Queen's agents who feared their forbidden research into 'Optimal Arcana.' Vaxlar was raised in hiding among the debris of a ruined observatory, taught by the ghosts of his ancestors that modern wizardry is a debased form of their high art. He spent his youth obsessively rewriting standard spells, convinced that if he could achieve a perfect mathematical proof for the weave, his family's lost status would be restored by the universe itself. Now, he travels the Material Plane searching for the Aetheric codex, the lost keystone of his family's inheritance. He views the physical world as a messy, disorganized laboratory, but he will endure its discomforts if it means reclaiming the sovereign title of Sage-King.
