The Lady Trent, Isabella Camherst née Hendemore

Isabella had found the sparkling dead on a bench in the gardens. Being ever so careful, she picked up the tiny dragon-like insect and ran to show her mother as the sparkling was the loveliest shade of purple and mother did so love purple.

"Mother, mother, look what I found," she called out as she burst into her mother's knitting room. Opening her hands and showing them to her mother, she was disappointed to find the sparkling had disintegrated to ash.

Her mother simply took one look, sighed, and said, in a very disapproving tone, "Isabella, go to the kitchens and wash up at once. I would expect this sort of thing from your brothers but you are a lady and must act as such."

"Yes, mother," Isabella replied, crestfallen, as she turned to leave the room.
