A paraphrased note containing info from a conversation with a Thorne mage will be left in the same place:
Regarding Arcana reversals, she explains that this only ever applies to its casting or its reading. For instance, if a card is drawn upside down, it may have an alternate effect or interpretation. The design itself is never inverted. Some variations in artistic style can occur like any symbol, but the core elements in this particular sigil have been altered which is unheard of. This suggests a new meaning altogether has been assigned to it as opposed to artistic liberty.
