Constellations and planets are what trolls are mainly based off of. All of the beta, alpha and ancestor trolls' are respectively known for representing a special zodiac. With an accurate and very characteristic personality of their respective star signs. Cherubs are also known to posses this as well, but only with Ophichus. A hoax zodiac in most countries of the non-eastern hemisphere.
Even the humans trollsonas appear to represent constellations. Like Jane possibly being the big dipper for example. Due to her passion for baking and cooking and her horn shape. Or the little dipper.
