Get past the annoying field by going to where the drayks are. Near that, a bit south I think, there are the drakons' stuff which you should steal. Neat that, I forgot the direction, is a place where it has a door that you need to pull a lever. I think that the lever is behind a pillar.
After that, which takes living tools, you go in and there's an energy spiral, which you can turn off at mechanics level something (14?) Once you did that, go back to the energy field, get the key, and go cause havoc.
