Look into the Eye of Eternity at the Nether Vortex in the Nexus.
Meet Tarecgosa inside the Nexus where she will escort you to the rift.
<Tarecgosa listens as you explain your presence in Coldarra.>
Your tale rings true, <class>. Much has changed since the death of Malygos - little of it for the better.
I know of the device you carry, and I recognize Anachronos' magic in its creation. There is but one place in all of Coldarra that would allow this Timeless Eye to be used discreetly.
You will require my assistance if you hope to succeed. Speak with me again inside the Nexus and you shall have it.
