The LOTR personality test this week says I'm like the Dwarves:
The DwarvesAs the halls of Moria show, Dwarves like building and inventing.
The world exists to be explained and analyzed. You prefer to work quietly without interruption. Time alone is important and solitary activities refresh you. You have a tendency to introspection. In your desire for clarity in life, you may have the tendency of being remote or even "heartless". You like keeping your options open. Closure is probably not one of your strong suits.
As the foil to Aragorn, Sauron clearly embodies the evil side of this personality.
Traits: Pragmatic, autonomous, ingenious, resolute. On the dark side you could desire power and domination.
