Minshina's Skull

I hear the voice of my brother, Minshina, calling to me in my dreams.$B$BHe was taken by Zalazane, the warlock on the Echo Isles to the east. And he is dead.$B$BBut death is not freedom for my brother. Minshina's spirit was trapped within his own skull by Zalazane's magics. In my dreams I see it with other skulls, in a circle of power on the largest Echo Isle. As long as it remains there my brother's soul is doomed.$B$BPlease, $N. Find the circle and retrieve Minshina's skull. Bring it to me.$B$BFree him!
