Fantasy diets

All creatures in the fantasy world require sustenance to survive. That said, these diets do not necessarily resemble conventional diets.

• Physical diets: the creature feeds on something physical, such as air, food, drink, soil, fire, warmth, etc.
• Abstract diets: the creature feeds on something abstract, such as color, shadows, emotions, memories, life force, psi energy, etc.
• Passions: the creature does not feed per se, but must fulfill a specific series of actions in order to sustain itself, such as mimicking a diet despite otherwise lacking any sign of digestion, tormenting victims in a specific fashion or pursuing unfinished business.
• Anchor: the creature has no diet or passions, but its continued existence is dependent on a physical or abstract anchor such as an amulet, a temple, a bloodline, or faith in an institution.
