Put simply, a plan is typically any procedure used to achieve an objective. Though planning can occur in any caste, only members of the First Caste are seen to formulate plans which achieve their desired objective. All other castes require the assistance of the First Caste in order to successfully complete their own plans. For the same reason, the creation of a plan is a sure way to ensure failure for anyone of the lower castes. One notable exception is the necromancer Rillian, who is able through unknown means to complete plans without the assistance of the First Caste.
