Riralian

Riralian is a collecting related gender that is like a stack of books. All genders are always present but tend to get reordered in how strongly and prominently they're ‘read’/felt (genderlead), some may even throw out papers if they're no longer felt, (purgecollector).

For example, one's books could be demigirl, neoboy, juxera, and ningender. They could be in that order but they may reorganise the stack of books to be neoboy, juxera, demigirl, and ningender instead, which means their leading genders have changed. One may also get rid of a book once it's no longer felt, purging it in turn. Also, one can add to the stack whenever they'd like, which may or may not include genders that one has thrown out already. This could be seen as recollecting books.

Riralian can be a stack of anything. For example, instead of a stack of books, one could say a stack of papers or files, etc, instead.
