Portal Magic is the Worst

After finishing the temple we moved to the arcanum. It was a fatiguing fight that saw us dealing with more grell, and a monstrous clay golem. The main chamber was divided into three doors all labelled incorrectly and thanks to enchantments left we were notified of the changes of room use. We decided the graviturgy research wing was the best location to start with as the portal research was probably going to be the main problem.
 
Graviturgy was both a resounding success, and a difficult loss. Upon entering the room we found several grell, their weird handlers the nothics, and a huge clay golem (which is more than immune to acid weapons it turns out). There were the glowing runes on pillars which when we used magic near them, would cause gravity shifts and draw people in or away based on the runic inscriptions. The fight was hard and left most of us too tired to keep going so after scouring the room (we found an interesting oil that could be of use entering the magisters hall) I found a refined altus crystal which I will be attempting to install in Toby as soon as we return to a position where I have the time and tools to do so.
 
We rested outside the arcanum and I used one of Celia's travelling potions to stay awake without side effects, I think the continued use may be building a tolerance to it's rather rough impact on my body. We reentered the arcanum in the morning and lay siege to the portal research room. Horrors came for us in the darkness of that wing. Made me see Oswald Street again... after recovering we pushed on and found the main chamber where the research was being conducted. A straneg being was floating above a massive rift in the planar space and after a VERY long fight that saw several major injuries, and every bit of our strength to overcome, we managed to defeat it. Upon its death the portals closed and the arcanum repaired itself from the damage wrought by the portal's continued opening over the past several thousand years.
