Disable the field stabilizers
Go to alternate dimension and disable devices
I just happen to be looking for a hero who can help me. As I travelled through the dimensions to get to this world, I came across one that I believe posess a great threat to my new found home. A world overrun by aliens, who were working on stabilizing a portal between their own world and this one. If you can dismantle their field stabilizer, I can help prepare you for what lies ahead.
The portal I have marked for you should get you to that world in one piece.
Instanced Outdoor [Terra Volta] (Rikti)
This world is overrun by Rikti. You had best find that field stabilizer before they find you.
Mission Complete: Field destabilized. Return to home dimension immediately.
Excellent work, Red Tomax. Those wierd aliens won't be able to make their way to this world now.
Well done, my friend.
