There are lots of unused NPCs and objects in the Morrowind data files. It's as if the developers never made any attempts to clean up anything, you can even find their notes to themselves. That prompted me to make a mod inspired by the “Cafe of Broken Dreams” special encounter from Fallout 2.
A strange Nord is relaxing on a beach on the Azura's coast (coe 19, -3). He can take you to a place where non-existent characters gather to complain about their situation. All those characters retain their original ids and inventory, I only gave them custom dialog with their background as I imagine it.
