These call on what is believed to be the ultimate
source of power, which differs from spell to
spell. Quite literally, they call up that power
and ask for permission to use this influence for
a stated purpose. Meddling with this power
and calling up negative forces is extremely
unwise and very foolish.
Spells for selfish personal power or to gain
power over others will often backfire on the
unwary and may cause damage to the
individual who casts them. Invocations of
positive forces can do no harm, except that the
results can sometimes be highly disconcerting
due to the sheer energy created, although the
eventual outcome may be good.
