Argyles mother is presumed to be a human female, and birth mother of Argyle, originating from the town of Plockton.
A human female with long red hair and green eyes
Argyles mother behaved in cryptic and irregular ways. Her interactions with Argyle while in Plockton seemed to be copacetic, but her eager adoption of a new suitor, Lord Serpentini, after the death of her late husband was questionable.
Upon arrival by the party to Plockton, it was discovered that Argyles mom was now engaged to Lord Serpentini and appeared to be acting under some kind of spell. After the invasion of the Serpentini house, she summoned two wyverns by singing from the top of the church. She was flown away to a nearby cave, where she was found locked behind an invisible barrier whispering to a stone bust of her late husband. After the part gained her attention in the cave, she sang an ominous song, seemingly foretelling the arrival of everyone there.[1:1]
While I don't currently have the exact lyrics, the jist of the song was:
she knew all of us by name, and knew we were about to journey. she said to trust nova and search for someone in argyles family whose face he would recognize, likely a sister.
After her song, she touched the stone bust of her husband and slowly turned into stone, then immediately crumbled into ashes. Argyle now carries a portion of her ashes with him at all times.
