Chief Engineer Boltwrench wants you to find Kibli Killohertz at the hidden Alliance airport above Aldur'thar, the Desolation Gate.
The goblins got lucky and found a new energy. They call it infra-green, and I'll be a one-eyed ogre if those psychos didn't strike green gold.
Go find Kibli Killohertz. He's leading the reverse engineering efforts of infra-green, at a small, hidden Alliance airport above Aldur'thar, the Desolation Gate. I'll give you infra-green vision to help you find it. Go to the dome with our Alliance banners -- if you fly near the Horde airport then you'll be in a load of green trouble.
