The twenty-first arcanum gives breadth. Such a person is interested in everything at once, moves easily between fields and knows a little about a great deal.
They are drawn beyond what is familiar — into other countries, languages and ways of living — and it is the right pull: their business is to join worlds together and to carry one into another.
The strength is the ability to explain one culture to another and to be understood in any surroundings. The weakness is superficiality: breadth comes more easily to them than depth, and stopping at any one thing is hard.
It comes into its own best where what is unconnected has to be connected.
