Rans Net was invented to catch fish as this Ring was made to catch the eye of those seafaring souls set off to find their own interpretation of gold. The symbol in this tungsten-laden sphere is to depict the joyous occasion that occurs when the Gold is found but also the realization that it is not meant to last.
Rán is a Vanir sea goddess with an unpredictable and dangerous personality. Rán is married to Ægir, a sea-giant, and together they have nine daughters (see Nine Daughters of Ægir) who are waves. However, that marriage doesn't stop Ran from having all sorts of affairs.
