48 Card Deck & Guidebook by Megan Wyreweden
From the creator:
The Nocturna Oracle Deck is the little sister of the Anima Mundi Tarot. An oracle deck is like a tarot deck, except without a specific structure or archetypes (major arcana, suits, queens etc.). For this deck, I chose mostly plants and animals that are active at night. The deck starts with the "dusk" card as the beginning of night, and ends with the "dawn" card, signifying the first light of day.
An accompanying guidebook offers suggestions on how to interpret the cards, however this is optional, and you can derive your own meanings yourself. This can be read on its own, or accompanying a tarot deck.
