I think this is an attempt to write a SF story in Lovecraftian mood (hence the language and setting). Lena is written as a hypothetical Wikipedia article.
It's an odd site design. Stories are loaded dynamically by script based on the URL fragment identifier; I'd imagine Reader Mode isn't geared toward that sort of thing.
