According to Moonalice legend, Necessity was the original matriarch of the ancient tribe. She was the mother of all Moonalice matriarchs, as well as of a young brave she named Invention Moonalice. Necessity's vision - which combined low tones with high spirits - unified the tribe and helped it thrive in a period of chaos. Known for innovation in agriculture, Necessity was the first to discover the benefits of culling male plants in the field. Her recipe for hemp brownies changed the course of Moonalice culture, as it allowed the tribe to resolve conflict through catatonia, rather than violence.

Even today, tribe members turn to the spirit of Necessity for guidance in times of stress. Her adage - "smoke first, then forget" - has been forgotten by many, but survives as the foundation of the modern 4:20 ritual.
