Talk to Nomarkh Jezerith, complete her tasks and those from her aides.

{username} and everyone... I suppose we have a chance to solve both of our problems: you will help us with activating the portal, and we will come with you to Xadagan so that we might report our discovery. Unfortunately, even though we've already managed to unearth the portal's entrance, its full activation is still far away. We've already solved almost all of our problems, but it's getting more dangerous out here with each passing day − Sardrok is nearby, and something odd is happening there.

We need to prepare everything for starting up the portal. Otherwise there's an off chance to be transported piece by piece.

Excellent! Now we have everything that is required for the primary job. Of course, the hardest part is ahead of us!
