It appears that Beritra has already arrived at Agony's Well, where Ereshkigal is sealed.

We need to get there and stop him before Ereshkigal is freed. Beritra does not act out of kindness... there is something deeper and darker behind his intentions. I sense an evil more hideous than I can imagine within those walls... one that he is trying to release.

I need you to first eliminate the Obstructers. They are the protectors of Drakenspire Depths, though they're now under Beritra's domination. Then you must vanquish Beritra and assist the Kismeti Detachment in capturing Drakenspire Depths. I realize this is a lot to ask, but this is what it's come to. It's now or never.

Player: Accept

Beritra.... You stood against Beritra and lived to tell of it.

We've taken Drakenspire Depths!

Player.... This is what legends are made of!
