While the lack of human psions remains a sensitive topic, humans (unlike the bitter and emotional Kruthandi) are practical enough to hire the talent they cannot possess, and have even built a small number of symbiotic civilizations with the more indulging of the Powers. In a galaxy where nearly all sophont life is specialized to a fault, humans have found the unique niche of occupying no particular niche.';
