Lacewing

Lacewing is a female western dragon who is mentioned in The Menagerie trilogy.

Appearance
She likely looks similar to her offspring, Scratch and Scritch. She has a tag in her ear.

Pre-Series
Lacewing laid Scratch's and Scritch's eggs and defended them while waiting for them to hatch. When Brigid Strong's parents came too close to Lacewing, she assumed they were a danger to her eggs and killed them. Brigid became vengeful of her ever since.

Krakens and Lies
Lacewing is mentioned to be in the Arctic Menagerie, along with Scritch, both of which were assumed to be dead. Later, Brigid, formerly under the alias of Delia Dantes, is exposed at the Wyoming Menagerie's saboteur, and she explains Lacewing as the cause of her motives.
