Speak with Kara the Valkyrie
The Valkyrie Arena is in Svaladal - you'll visit it as the first Heroic Saga is obtained. In the screenshot above we have shown where the arena will appear. You can take part in battles on it as soon as you get to this region and unlock the first heroic saga.
Arena fights involve facing various opponents, including legendary animals of Asgard. Heroic sagas (as battles are called) consist of several chapters, i.e. several waves of enemies. You enter the battle with your current weapon, armor, and powers and abilities you've unlocked.
Collect all of the Heroic Sagas
You will find 12 heroic sagas throughout the land. We have described their locations on separate pages of this guide:
Collecting all heroic sagas will complete the mission.
