Nimbus

Starshine’s mother and mentor as a hero, Sarah Levi was a heroine called Nimbus, a specialist in weather magic who worked quietly for several decades.

In Fiction: Night Sky Comics
In the context of Night Sky Comics, Nimbus was originally created during the Golden Age, a magical hero who fought in World War II. She initially had very little personality, but as the most well-known magical hero she got much more focus in the Silver Age, becoming the forefront of many magical stories in Strange Comics, and was fleshed out as a dour woman with a dry sense of humor and a hidden flair for drama. This is also where her romantic interest, David Levi, was established.

Over the course of the Silver Age, Nimbus ended up shifting into a mentor role in Strange Comics for characters like Counterforce, and was aged up a bit - she was given a daughter at home who she focused on raising to explain her increasing absence which, out of comic, was done primarily as her weather control was considered too powerful for the stories that the writers of Strange Comics wanted to write.

Nimbus would occasionally appear as a mentor figure in Strange Comics and in Starshine, but would largely be a background character, and her appearances have been rare since the introduction of Starshine - although she occasionally assisted in teaching Vega magic.
