Omnia Oscura Playing Cards
The main Omnia theme is cyclicality, especially in the sense of something constantly re-creating itself, the eternal return. The main symbol is the Uroboros, the immortal God-snake who eats its own tail, represents the beginning and the end of time.
There are three different Omnia decks, and every deck represents a dimensional plane in the Omnia Universe. Oscura is the dark side, Illumina the bright one and Suprema is the plane where the Gods live.
Every court live a different reincarnation in each deck: in Oscura their soul is more dark, they are more malicious, angry or sad. In Illumina they are much more happy, brave and generous. In Suprema they are ascended to Divine, and show their power with elaborate armors, jewels and wings. Think every deck as a different mirror, who reflects every Omnia court with a different soul.
