Davia Pledge

Davia Pledge is a reclusive composer and former socialite known as "the Mad Composer of Sapodilla". She is controversial and taboo amongst the upper class there, but also highly popular. 
It is rumored that she invites people to private concerts at her residence, after which they disappear, but no one is ever able to name more specific details. Within the past year, Davia also has been releasing "Pledge Cylinders", the first recorded music in the heartland outside that from the Blackwick Mines. These records, resembling real life phonograph canisters, are in a syncopated style resembling the jazz in the Sleeping City, and affect their surroundings magically. 
After the death of her partner Lady Ziziliana Esterhazy in the fire at Pledge House, Davia planned to destroy the Glim Macula and the remaining aristocracy of Sapodilla, believing that they were responsible and that there was nothing worth preserving within the city. She used the energy provided by splitting the Remembrance of the Zahir into two halves to kickstart the operation of a machine that would take decades to build up its strength enough to finally destroy the city. 
However, once unleashed, Virtue Mondegreen thwarted this plan by absorbing the energy of the Oratorio for her own nefarious purposes. In despair at having lost her life's work, Pledge met her as she emerged from the underground, and the two conversed about their view of Sapodilla. After saying goodbye to the god she had cared for, Pledge walked away along the beach.
