Practical Analysis

I have one hypothesis that may explain a lot. However, due to outdated measuring equipment and extremely large tolerances that I cannot reduce... Anyway, we will have to work just like in the old times, using any means available. Purely theoretically it is possible to identify some properties of the Astral that surrounds Irdrich indirectly, i.e. by its influence on matter.
Don't worry, you won't have to jump into the Astral. But, I must admit, that would have been an interesting experiment and even somewhat amusing for me, albeit not terribly productive. Therefore, you will still have to toil in the name of science and collect research material.
At the shore, where the Astral contacts hard matter, you may find minerals subjected to its erosive impact. While the albatross living near the shore are not warped, their eggs were likely impacted by the astral. So if you can collect ten warped minerals and eggs, then I can make some initial conclusions. I can find a reference point that may turn our understanding of the Astral upside down...

So where are my long-awaited samples? My work is at a standstill without them!

So, I have living and dead matter. It would be nice to acquire matter from demons living in the local Astral, but without ships it is impossible. Except by slitting the throat of some dumb assistant in the name of science and baiting demons with their blood.
