The Path of the Unwritten.
Daughter of the elf merchant Matthias, Harmony was travelling to Telsca along with a wagon of goods when a force of kobolds attacked. Rather than killing the occupants of the wagon and stealing the goods, the kobolds captured Harmony and dragged her off to their lair in the glass ruins of Drakewood clearing.
The party arrived just past the completion of a dark ritual that, from the ranting of the kobold leader, had evidently failed to work as planned. Harmony was rescued from the sacrificial alter and revived, to be taken home and reunited with her father. As a thank you gift to the party, the mute girl gave them the amulet she had snatched from her tormentors, and used her innate talent to imbue the clerics holy symbol with magic power.
