SCAN
Syntax: scan [direction]
This command scans in all immediate directions and shows all creatures and
players in adjacent rooms. If a direction is given, the character looks deeply
in that direction for creatures and players. The range of this scan method is
about three or four rooms and is dependent upon light conditions.
Note: Normally, only the general size of the creatures scanned are shown;
with the farsight spell, the actual creatures can be scanned.
