The thirteenth arcanum is about transformation. It is not about an ending but about the old having to give way to the new, and such a person always turns out to be the one who brings this about.
They cannot bear stagnation. Where everything has settled down, they are the first to feel that it is time for a change, and they take it on even when nobody has asked them to.
The strength is the ability to carry a change through to the end without taking fright in the middle, where things are worse than they were before. That is exactly what other people usually lack.
The weakness is breaking something before there was any need. The thirteenth arcanum would do well to check whether a thing has really outlived itself, or whether it is simply bored.
