Borgun is a dense mass of weathered stone-colored skin and humming machinery. He stands wide and immovable, like a mountain ridge. His most striking feature is his beard, which is not made of hair but is a thick growth of translucent quartz shards that chime softly when he moves. He smells strongly of ozone, hot oil, and ancient dust. His left arm is a heavy, steam-hissing prosthetic of brass and silver. In his forehead sits a third eye, a polished sapphire lens that glows with a faint amber light, scanning for structural weaknesses in the world around him.
