Oh my god! A horrible mistake! I forgot couple of absolutely fabulous mods!
Legendary Weapons (by farrp (sp?). Adds a ton of new special weapons with unique models made by various users. They are in leveled list so they are randomly spreaded thru morrowind)
Haunted Tombs (makes tombs haunted!!! All kinds of creepy sounds and some objects, like bones, are poltergeist possessed and might fly towards you with damage.
