We were inspired by the classical Tarot deck. We transformed it with the respect to deep symbolism of Tarot.
Limbus world itself was largely inspired by cards. When we were creating the deck and the setting, we studied Western esoteric traditions and the secret teachings of the East thoroughly. Then we dove into deep semiotics, and learned the secrets of modern post-structuralist psychoanalysis and much more.
So it is not surprising that the figurative style of our cards is characterized by a variety and richness of interpretations.
