Aurora Borealis is a Norse myth technology in Age of Mythology that is available to worshipers of Freyja and can be researched at the Temple. Once researched, it upgrades Valkyries into Shieldmaiden Valkyries, increasing their attack by +50% and their healing rate by +33%.
Note that in the Fall of the Trident campaign, the hero Valkyrie Reginleif is also affected by Aurora Borealis.
History[]
“ | The aurora borealis, or "northern lights", consist of flickering rainbow colors that can be seen in clear skies at high latitudes. The lights were said by the Norse to be caused by the glittering armor of the Valkyries as they rode across the northern night sky. | ” |
