Valthendril is a skeletal figure of faded elven elegance. His skin is the color of wet ash and clings tightly to his cheekbones. His most striking feature is a collection of hundreds of crude, black-ink tattoos depicting eyes of various sizes that cover his arms, neck, and even his eyelids. When he closes his eyes to sleep, he appears to be staring back at the world with a dozen more. He moves with a jerky, bird-like precision, often pausing mid-sentence to tilt his head toward the Black Pit as if listening to a distant voice. Despite his filthy state, he maintains a paradoxical sense of dignity, sitting upright even when resting in the mud.

Whisper is possessed by a chilling, quiet intensity. He is deeply polite to strangers but dismissive of their safety, often offering helpful advice on how to best listen to the Pit's vapors. He possesses the intellectual arrogance of a Morgrave professor trapped in the body of a beggar; he will lecture a common thief on linguistics while picking through trash for a crust of bread. He experiences sudden bouts of profound melancholy when the Hum falls quiet, believing he has somehow offended the entity below.

Formerly a rising star at Morgrave University in Sharn, Valthendril specialized in the linguistic history of the Age of Giants. His career ended abruptly during an expedition to the Blackcaps where he first heard the Great Hum. He claimed it was not wind or seismic activity, but a Cul’sir dialect song of mourning. When the university cut his funding, he refused to leave. He has spent a decade in Black Pit, selling minor secrets to the local black market to fund his ink and parchment, all while slowly tattooing more eyes onto himself to catch a glimpse of the singer he knows is down there.
