So this Transparent Discus comes from an Anubite? Then maybe I can used it to summon a soul.

Because the Obelisk knows who the captured soul belongs to?

Do you want to help us find out the cause of the Anubites' appearance?
I will now summon the spirits so that you can talk to them and find out the reason for the Anubites' appearance.

You must then return the summoned souls to the flow of Aether, Player.

Are you ready?
We absolutely have to tell Liske that the Anubite used to be a Daeva.

Thank you for your help.
