1) The southernmost and northernmost are considered south and north, respectively, while those closer to the center are considered west and east.
2) The statues are arranged as follows (unless Revan assigned them numbers purely for convenience):
9 - Nothing
8 - Order
7 - Death (?)
6 - Nightmare
5 - Despair
4 - Power (?)
3 - Lust (?)
2 - Curse (?)
1 - Time

incorrect.
