How do poets and writers typically describe death

In most cases, the way that they will describe it is by using imagery to indirectly descrbe it. However, sometimes the author/poet may choose to outright speak it out, though it detracts from the overall tone of the passage.

  this riddles' answer is library.

  the "leaves" are a reference to the books' pages that the library contains; the branches are a network of libraries that connect multiple libraries' collections, resources, and items in a system of a common database, integrating them; the branches' organization are a useful management tool for coordinating the multiple collections many libraries have.
