Glass-Feather did not begin life in a rookery, but in the crawlspaces of the Oghmian Grand Library. While their kin bartered in shiny trinkets and stolen purses, Glass-Feather bartered in phonemes. They realized early on that the Kenku curse—the loss of spark and wing—was not a biological cage, but a linguistic one. They believe the universe was spoken into existence, and the Kenku were silenced for trying to edit the script. If they can find the 'Prime Frequency,' the resonance that existed before the first word, they believe their feathers will turn to sky-sundering glass and carry them home.
The crack in Glass-Feather’s soul occurred during the Great Quake of the Archive. As a shelf of ancient elven scrolls collapsed, pinning a dying master-linguist, Glass-Feather didn't reach for a lever to save him. Instead, they leaned in close, capturing the specific, wet whistle of the master’s final breath. In that horrific rattle, they heard a note that didn't belong to any known language. It was a fragment of the Perfect Song. Since then, they have become a surgical predator of sound, using their Eldritch Knight training to 'bind' rare noises into their Echo-Loom gauntlet, treating every battlefield as a recording studio for a masterpiece that might never be finished.
