summon

Syntax: cast summon \<character\>

This spell summons a character of your choice from anywhere else in the world
into your current location.  Characters or mobiles who are fighting may not
be summoned.  Mobiles may not be summoned outside their own area.

You may not summon mobiles who are more than 2 levels higher than yourself, or
players who are not in your group or clan and do not have their summonable
flag set.  See 'help config' for further details.
