Those books by the way were just a result of googling around different words from the text provided, and mixing and matching with the oroboros, finding Lovecraftian poems and so on, and landing on this fantasy series which, quite honestly looks like an amazing fit for an RPG series, the maps for the book settings were created by a naval cartographer and so on, the fantasy includes morality questions and the futility of repeated actions, and is a good v evil setting of sorts. Plus the books deal with the ouroboros, and the setting is Norse-like, similar to some of the language, and it's written in a very formal 16th century English way.
Anyway, this is my guess after all of ten minutes worth of research.
