[WolfWinter]

She is tied to the new moon. She is able to more regularly enter this plane than her brother, however, she has fewer opportunities outside of this to visit physically. She is able to visit partially if the area she wishes to visit has an ice halo around the moon. The bindings that tie her to these aspects of the moon are still tight and don't allow her to visit outside of those circumstances. Her brother Harvest was originally bound to only the harvest moon, but has found a way to loosen his bindings so that any situation similar to a harvest moon is an opportunity to visit.
