So the last time I was a bit stuck in Planescape: Torment. It turned out just buying a lot of stuff from the curio shop let me progress. I now have the key to the portal to Ravel.

I also figured out that I already had my journal with me for a time, I managed to read it and I have gained access to the Foundry. Just as with my earlier hiccups with the game, it turned out I just need to pay more attention to make progress. This is not a game that you can play casually. You have to make the connections. So when I almost fell asleep talking to all the characters in the new area, I realized I had to quit and come back another time when I’m more alert.
