Adana is being slowly restored to normal humanity via Clarissa's care, and at times, Paraswarm's efforts. The system for this is that each month, roll a d100 against her current humanity score; rolling under the score indicates that a d6 may be added to her score. Clarissa gets -20 to her roll, due to her skills; Paraswarm gets -10 to his score if he communicates mentally.
See the Humanity chart for what specific values mean.
