Description
This is a teleportation device. If I had to guess, I'd say that it leads to the surge needle platform floating above the Moonrest Gardens to the southwest.
<name>, I need you to use it to investigate what's up there. It appears that the device works both ways so you shouldn't have to jump off.
I expect that once you teleport up to the top of the surge needle, there will be some sort of apparatus on it to observe.
You should be able to use the teleporter from anywhere within the gardens.
Reward

The Arcanomicon is a map of all of the magical ley line intersections in the world. The blue dragonflight has been using it to find and destroy ley line 'anchors' to send the magical power back to the Nexus.
The question is, why is the path of destruction leading east when it should be heading west instead?
Gains
