Reign of Winter (PF1E)

At the bubbling cauldron the party fought a creature that appeared to be made of air that could surround them, but was able to defeat it. They then enjoyed some time trying different spices from the table in the cauldron and eating the contents, some of which were quite good. They then moved thru another passageway into a small cavern separated by a large column in the middle. Most of the way into the cavern, the party was ambushed by shadowy figures that could sap the strength from anyone. Sadly, two of the party perished before the shadows were defeated.
