the golden sword of Hrotti which is part of the treasure beloning  to the dwarf/dragon Fafnir who curse the sword with his dying breath after sigurd killed him for it : who ever own the sword will have unlimited wealth but the downside is you will die by the one you loved the most and you know that they will kill you but there nothing you can do to stop it.

how to destroy it: you don't you must return it back to Fafnir cave in order to stop it.

side-note:  Fafnirr warns Sigurd that all who possess the gold will be fated to die, but Sigurd replies that all men must one day die anyway, and it is the dream of many men to be wealthy until that dying day, so he will take the gold without fear.    to put it simply he did not care.
