The H.E.L.M., The Moon's Orbit
Eris has returned with a bounty of information pertaining to the new state of being created in the ritual. The Guardian meets with Eris at the Crown of Sorrow in the H.E.L.M.
Eris Morn: With change comes opportunity. In studying this "memory" of Uldren Sov, a truer nature of the Nightmares is revealed. They are born of Darkness, and drawn to it like moths to a flame. Calus is such a fire. Through the Leviathan, Calus's mind reaches down to the lunar Pyramid, forging the connection that draws the Nightmares to him. And should that connection be severed…
Zavala: We can stop Calus dead in his tracks before he causes any more damage. Your success with Crow isn't going to go unnoticed. Calus will push back… he may be doing so already. Recently, I've been… visited in the H.E.L.M. and elsewhere. By one of the Nightmares Eris bound to the Crown. We need to push harder. I will be accompanying in your next severance mission to weaken Calus's connection to the Pyramid. You and I will get this done.
Eris Morn: Go to the Leviathan and harvest the necessary essence of the Nightmares. We must enact the next ritual of severance before it is too late. And Guardian… keep watch over Zavala. As with Crow, the commander may find confronting his past to be the most difficult mission he has ever faced.
