Creio tratar-se de livros. Entendo que tal colecao de volumes/titulos seria completa e incluiria contos/historias sobre dragoes.

Espero que ajude.

To visit on/upon: to do something to punish someone or show them that you are angry.

Os livros de nossa coleção podem sair/se deslocar e se visitarem para punir os dragões no campo.

Estou aqui usando minha imaginação.

Creio que os volumes são personagens vivos que se movimentam e fazem coisas juntos.

sozinho pq '' visit themselves upon'', os livros que iam themselves para castigar os dragões

castigar pq achei legal entre todos o sinônimos..

lá fora devido ao '' go forth'' ( sair), e do out (ainda que sair lá fora ser pleonasmo, mas acho q fica legal)

Main Entry: visit upon
Synonyms:

The idiom "to visit oneself upon someone" should not be parsed into something containing "vistar" e "mesmo" (to parse idioms into individual words is usually a very bad idea). The same goes for "out in the field" regarding something containing "campo". Instead, "por aí afora" is a Portuguese idiom the fits both the intended sense and the context. That being established, "to visit oneself upon someone" is not quite "to punish someone" ("castigar alguém") but rather "to make some (kind of) impression upon someone".
