Collect a Pure Solium Band from High Sage Viryx in Skyreach.
I have much to ask of you, <name>, but before we begin I must ensure that you develop yourself to your full potential. I can help.
I'd like to create a link between us, an artifact that will enhance your power and allow me to track your progress. How do you feel about amulets? No? A ring? I've got it.
My contacts among the arakkoa outcasts tell of a band of pure solium. Right now it's in the talons of High Sage Viryx high atop Skyreach. Bring me that ring, <name> - you and I have much better uses for it.
