To move things along, you take whatever items you want from Malissin, make it back to the top of the "hole," and go back to the point where you fought the giant visperillion viper creature. So you are now back there, with a freezer full of meat to the west, a large door still closed with the pulley system to your south, and a tunnel leading north, back the way you had come, as long as the other exits noted in the map below:
The two primary points of interest are probably the following:
1) The large shelf-like tunnel that led to the east, which you did not ascend, and instead came south; and
2) the large door to the south that you have not opened.
You take an educated guess that the other western corridor probably leads back toward where you were just at in the hole.
