What is this?

This particular page is a directory that contains some longer-form writing that either I did, or that someone else did, and that I want to preserve and share for whatever reason. It’s basically a collection of essays, plus some other stuff like fantasy world guidebooks and things that I’ve ran into and/or saved over the years. The main prerequisite is that the things here must primarily be some form of writing, which is why thematically the page name references letters, both in the definition of written letters that are placed in envelopes, as well as letters of the alphabet jumbled up like fleeting thoughts.
