Go to King's Gorge and talk
to Agritt.

Show Quest Info

Introduction

Not much is known about the dark forces. Even Muto does not know where they came from. In order to conserve resources, Muto has decided to put the investigation of the dark forces aside for now. Since you are now a demigod, it is time to meet with Agritt again.

NPC Dialog

Now is not the time to investigate the source of the
dark forces. We must first focus on Odin's revival.
According to Agritt, one must possess a god's
strength to pass into the netherworld. You now have
this strength, thus the time has come for you to
meet with Agritt again. He can help you obtain
Pandora's Box.

Quest Completion

Don't kid yourself, you're not getting into the
netherworld. Being a demigod will not help. After
Ragnarok, the god of the underworld permanently
sealed the gate to totally sever connection to your
world. If you think about it, we would not have
remained in King's Gorge for this long if it was not
true.
