Lord of the Rings Online - Dread @ Official Site

Keth, a Senior Designer from the Lord of the Rings Online team, explains the game's dread system at the official site.

The initial inspiration for the system was what I was calling the "evil-o-meter." I just imagined getting near some source of great evil, such as the Witch-king, and watching a needle peg all the way to right. And it's hard to explain, but imagining that in my mind made the situation that much more intense and cool. For some reason, that completely artificial mechanism added an important layer to the scene. Sure, we try to convey evil through our art, sound cues and other sources, but it just seemed really awesome to me to really tell you, the player, that, "HEY, THIS GUY IS EVIL!"
