This Skyrim mod adds a Shadow Of Mordor-inspired Nemesis system

A new mod for Skyrim: Special Edition draws inspiration from the Middle-earth: Shadow Of Mordor series by turning regular enemies into powerful Nemesis versions if they kill you. Rather than simply die and reload a save, you'll respawn elsewhere in the world, ready to hunt down your new named Nemesis. They might even loot your gear and use it against you.
