Helandra is the Ardic goddess of secrets and of the night. As such she is the patroness of thieves. She also represents the largest of Ardrana's four moons. She is often referred to by the appellation "Lady of the Night". She is served by both those who keep secrets and by those who seek to discover those of others, which leads to her also being the patroness of the Investigators' Guild of Nazivonema.
Helandra's holy symbol is the crescent moon. Her worshippers consider the colors black and pale yellow to be sacred. Her priests are often skilled at the roguish arts as well as divine spellcasting, leading to others often calling them Shadows. The Outlanders, which as planets are only seen at night, are sometimes thought of as servants of Helandra, depending on the culture.
