cast 'continual light' <target>         cost: 13 mana

   Continual light is a low level cleric spell, one of the first that can
be cast by young clerics.  Invoking the spell involves the offering of a
small prayer for guidance and light.  When the spell is cast, a small ball
of light is created to guide and light the way for the target.  The ball
will stay until destroyed with the 'dispel magic' spell.
