The Senior (binary 10010) is the 19th Major Arcana card in this Tarot deck.
The Moon is a symbol of intuition, dreams, and the unconscious. Its light is dim compared to the sun, and only slightly illuminates the path to higher consciousness winding between the two towers.
This card is represented by an entity that is in another level, through their fights and findings, they achieved the seniority. The Senior is wise and experienced, but also always humble to know that even though we are experienced, we are still ignorant in a lot of things and the duty of the senior is to pave the way to the junior and to guide them to become seniors in the future so the senior can finally retire in peace.
