 After stanza 18 , a prose narrative relates that Helgi and his immense fleet of ships are heading to Frekastein , but encounter a great storm . Lightning strikes one of the ships . The fleet sees nine valkyries flying through the air , among whom they recognise Sigrún . The storm abates , and the fleets arrive safely at land . Helgi dies in battle , yet returns to visit Sigrún from Valhalla once in a burial mound , and at the end of the poem , a prose epilogue explains that Sigrún later dies of grief . The epilogue details that " there was a belief in the pagan religion , which we now reckon [ is ] an old wives ' tale , that people could be reincarnated " and that " Helgi and Sigrun were thought to have been reborn " as another Helgi and valkyrie couple ; Helgi as Helgi <unk> and Sigrún as the daughter of Halfdan ; the valkyrie <unk> . The epilogue details that further information about the two can be found in the ( now lost ) work <unk> .
