OBSCURE
Usage:

      obscure
      obscure <target pc>
      obscure none

Obscure is a ability that Ordained Mortals have, which can hide them
from one PC in the game, so long as the target PC is not also an Ordained
Mortal. With no arguments, the command shows who you are currently
obscuring from. 'obscure none' turns this off.
