I found some more great information about Rán here - http://reclaimingthedarkgoddess.blogspot.com/2010/03/ran-norse-goddess-of-sea.html
From the link:
"She has been called cruel, greedy and insatiable. She reigns over the the Underworld found at the bottom of the sea. Ran mated with Her brother, Aegir, the sea god, and they had nine beautiful daughters, the Waves... Her name means "robbery", and She could often be found lurking on the dangerous cliffs and, with the help of Her daughters, enticing mariners to approach; once within Her reach, She spread Her fishing net over them and calmly draws them down into Her realm.
"The Norse people believed that drowning victims were not admitted into Valhalla; instead, they went to Ran's realm of the dark. She was, therefore, also considered to be a Goddess of the Dead. If the dead had gold, they were treated well within Her deep sea abode, and the mead would flow freely... Ran represents water; and, as such, She controls the life force of all the creatures on Earth."
