It is a fortune-telling using "Grand Ettira" published by Grimaud of France.
The Ettira Card was created around 1780 with reference to astrology and the Egyptian Book of Thoth.
There are 78 cards in total, but this app uses 22 cards called the Major Arcana.
Each card has only an abstract meaning.
Originally, you should understand the meaning and answer in a meaningful way, but this app can't handle that. This is an issue for the future.
I made this application if the card can help you to eliminate your own moyamoya.
You are the one to worry and solve the problem.
