FARSIGHT
Syntax: cast farsight
The farsight spell expands the caster's consciousness, allowing him or her to
see far away beings as if they were in the same room. With farsight in effect
the caster may use scan to actually see creatures and players in adjacent rooms
(not just their sizes). Also, with farsight, it is possible to look through
portals to see what's on the other side; without the use of farsight, this is
not possible.
Note that you must use the following command: look in <portal>
The 'examine' command will not work!
