The Fool - Beginnings, Innocence. The Fool is Marceline’s first major vampire kill and her first vampire soul sucked.
The Empress - Fertility, Nature. The Empress seduces Simon and craves blood and sating her natural urges.
The Hierophant - Tradition, Religion. The Hierophant wants to go back to the old ways of vampires.
The Moon - Fear, Mystery. The Moon intentionally terrifies her prey. She messes with them, and her motives are unknown.
Strength - Patience, Courage. The Vampire King was patient for the time to come for the ressurection of his species. He faces the future with bravery and welcomes the challenges that a new era presents.
Judgement - Judgement, Inner Calling, Rebirth. Marceline’s feelings and her desire to grow up is what drives her to start hunting vampires and make herself mortal. She judges them for their attacks and making it her goal to eradicate them. And her decisions mark a rebirth and new beginning for herself, vampire kind, and the world.
