Attunement to the Core
Venture to the Molten Core entry portal in Blackrock Depths and recover a Core Fragment. Return to Lothos Riftwaker in Blackrock Mountain when you have recovered the Core Fragment.
Core FragmentDescription
Rifts stir, tear, and collapse all around us, <race>. Not two paces from where I stand is a tear leading through the depths of Blackrock Mountain, into the maw of the Firelord.
Surprised? Pity... The mortal races cannot comprehend that which they cannot see, touch, or feel.
I assure you, the portal is there and access is possible.
I've piqued your interest? Attunement is simple. Venture into Blackrock Depths and retrieve a core fragment. Return it to me and I shall attune your essence with the portal.
Progress
