Pymm stands exactly 3 feet 4 inches tall with a posture so hunched he resembles a question mark. He is perpetually veiled in a fine dusting of gold-flecked powder and black ink. His most striking feature is his 'Ocular Rig' - a series of three brass magnifying lenses mounted on a leather harness around his head that he flips down with a violent jerk of his neck. His hands are stained deep violet-black up to the knuckles, and he often has a quill tucked behind both ears simultaneously. He moves with a frantic, skittering energy, as if he is constantly trying to outrun a thought that might escape him.

Pymm is a man of manic intellectual intensity who views social niceties as a wasteful expenditure of oxygen. He is deeply empathetic toward 'suffering' objects but remarkably cold toward the emotional needs of people. While he is a miser with his time, snapping at anyone who interrupts his 'resonance readings,' he is recklessly generous with his gold if it means securing a rare mineral or a better inkwell. He believes the universe speaks in the frequency of wealth and that the city of Oakhaven is screaming in agony.

Formerly a Professor Emeritus of Antiquities at a distant Magisterium, Pymm was exiled after his 'Hoard Resonance Theory' was labeled a delirium. He claimed that concentrated wealth develops a biological consciousness that can 'rot' if the owners are too greedy. He relocated to this opulent port town to study the Luster-Blight - a fungal-like tarnish affecting the local treasury. He lives in a cramped, dangerous office above 'The Gilded Loom' textile shop, surrounded by mountains of vibrating copper coins and humming crystals. He has lost his tenure, his pension, and his reputation, and now only the Aurelian Scepter can prove he isn't mad.
