The High Priestess is associated with intuition and the subconscious (dreams), as well as the divine feminine (like Artemis). Reversed, it can mean secrets and becoming withdrawn. So, naturally, I went with Luna, who certainly fits the upright version of the card, while the inverted card is reminiscent of her corruption by the Nightmare.

Symbolism here — the pomegranate evokes the myth of Persephone as a symbol of fertility and divinity. The pillars represent dualism. The veil represents the hidden nature of the subconscious, and the dark blue robe is for tranquility and meditation.
