Dear Professor Demoyen,
the progress you've made exceeds my wildest expectations.
I wish I could be with you exploring these new regions.
I've attache some of my latest calculations to this letter.
I believe we can penetrate even further towards the heart of this plane.
By creating a group of portals and diverting some of the power of the generator you should be able to make a short exploratory journey.
I can't wait for your next letter.
Professor H Morovar
There's a big pile of notes containing some very meticulous and complex calculations pinned to this letter.
