In Strange Aeons: Lovecraftian Numenera by Monte Cook and published by Monte Cook Games is a supplement for the Numenera setting of the Cypher System. The supplement provides some rules for using the works of author H. P. Lovecraft in a Numenera game.
The supplement is available as a 13 page PDF from RPGNow, with a full price of $2.99 although it was purchased at a discounted price of $2.24. The supplement is in full colour, and one page is the front cover, one page the recommended reading, primarily the most appropriate Lovecraft stories as well as some suitable comics, movies and games - the last, naturally, including the most well known game based on Lovecraft's work, Call of Cthulhu, and an illustration (there are also quite a few other illustrations throughout) and there is a one page advert for other Numenera supplements.
Part 1: Bringing Lovecraft to the Ninth World is about incorporating the Mythos, including how much of Lovecraft's magic could actually be considered to be science, into Numenera, as well as how to run a horror game and incorporating sanity, probably the most important factor in any game based on Lovecraft's work. It also considers that how Lovecraft's stories work bears a lot of similarity to how Numenera does anyway, so adding a Lovecraftian influence is fairly logical.
Part 3: Lovecraftian Creatures provides game stats for four of Lovecraft's creations, the Deep Ones, Great Race of Yith, Mi-Go and Shoggoths.
In Strange Aeons: Lovecraftian Numenera in Review
The PDF is well bookmarked, considering its size, with bookmarks for every section and subsection, even though several of these bookmarks just end up on the same page, although it lacks an index. The actual length of the book, when removing those pages that lack content, and considering the illustrations throughout, is probably around nine pages or so of actual material. The illustrations are good, and are in full colour, but they do take up quite a lot of space.
The supplement has two columns of text for Part 1 and Part 2, but only one for Part 3. Most of the pages also have sidebars, apart from the main text, which provide the front matter, extra descriptions, page references to both this supplement and the core book which are relevant to the text on the page and, for the four creatures, GM Intrusions.
The supplement does not stand by itself, but it is not intended to, as it is supposed to complement the existing Numenera game world, although it could possibly be used for other settings using the Cypher System, which isn't just limited to games published by Monte Cook Games.
The quality of this supplement is high, but the price is on the high side as well, for what is realistically quite a short book. There are only a handful of monsters that have been adapted to the Cypher System - there are far more than these four available. In Strange Aeons: Lovecraftian Numenera is a rather short treatment of a subject that requires more written about it and, in the majority of game systems for which a Lovecraftian supplement has been made, usually does have much more coverage.
