Who is Cornelia?

Meet Cornelia, the messenger pigeon of the Sand Castle. She is one of the four Heralds who live there. Before you say anything about her not looking anything like a pigeon, let me clarify that, for reasons I don't fully understand, she sometimes takes the form of this pink rabbit creature with horns, and other times she takes the form of a strange bird, with a long neck and black and white stripes. These are things that sometimes happen to subtle bodies, they tend to change shape very easily, sometimes for no apparent reason.

Illustrated postcard in a somewhat cartoonish style, of a creature that looks like a hybrid between a rabbit and a cat, pink in color. It has two small black horns, a white furry neck, and a tail that ends in two points. The legs have black stripes, and on its belly it has a green pocket that appears to be sewn on. Behind it is a bird with a long neck, black and white stripes. Both characters are on a rocky planet full of craters and spider webs with spiders emitting a blue light.

Cornelia is extraordinarily efficient, fast and responsible when it comes to transporting messages far, wide, high and deep into the U3P. We are on very good terms with her, she seems to like us, and she has no problem helping us. It is in large part thanks to her that our collective is able to be well intercommunicated in this particular universe. Although she doesn't talk, or at least she doesn't talk to us, after all these years we are sure we can trust her.

Her limit is that she cannot carry physical objects, only messages and subtle compressed information that fits in her pocket (the green patch on her abdomen), so we often have to synthesize the information in the best way we can.

This postcard shows Cornelia posing in both rabbit and avian forms on one of the outer planets of Side B, called “The Bird Theater”. I wonder what she was doing there that day?
