In the early literary environment there were free floating letters, 32 of them known from fossils such as Silas Mariner and Hamlet. Some of those, such as the letter Squizzy and Gnurple went extinct because they could not survive the telegraph and later the internet. Being slow letters, you see, they were outcompeted in the mad rush to broadband.
Those letters formed the first words in the paleoliterature era, some still fiercely independent like "a" and "I", but others forming symbiotic relationships between consonants and vowels yielding syllables and finally more complex words.
Sooner or later ecosystems formed, and words found niches within them, becoming verbs, nouns, adverbs and a bizzare form called the g'numph which was an evolutionary dead end.
It was in this environment that the Chronicles of Narnia arose as the pinnacle of evolution.
