When you first get to Morheim you will only be able to gather a few of the Big Vortexs that require 100 skill and are closer to the ground. Below is a map to show you where each of the Vortexs that require 100 to Gather are.
When your skill reaches 125 you will want to focus on the Big Vortexs that are even higher in Altitude. Below is a map to show you each of the locations of where you can find the Vortexs for 125 skill in Morheim:
When your skill reaches 150, the Vortex's you need will be a tad bit higher up in the air. At this point I recommend landing somewhere above town, instead of ground level to rest.
So, I figure that this guide will give you the jist of things but what I can't do is cure your boredom. And lets face it, you're going to be bored. So, here is a set of links with things that I think will entertain you.
