I feel bad for the low rating so I feel obliged to explain why.
1) I was expecting more. 9 pages is the listed count, over half of that is taken up with images. Page 1 is the cover image, page 2 is essentially an inside cover image (which would have been fine if the file had been much more substantial) 3rd page is the credits which of course is required, page 4 and 5 are just images. Page 5 has an image of a wolf which is just barely offset but gives me the impression this was placed to stretch out the page count because it really isn't needed. Same thing with page 6-9. In some cases, such as the cover and the image of the man on the final page, they look like they were stretched or otherwise not sitting proportionally. Layering the book cover in a graphic editor allowing the adjustment of the two figures without having to play with the proportions would make it look better.
2) The word count is very thin and it's riddled with gramatical errors. For example: "Thatdoesn’tmeanallLhiannan are like captain planet." or "They sand fiercely independent, while some....". Some of wording might have been mashed together due to whatever publisher program was used but others are just odd mispellings and punctuation issues. Going back and plugging it into a program like Grammerly or handing it to an editor might help.
3) What information that is provided doesn't cover what it's primary purpose is for: How did the bloodline survive? All we are given is basically: yes they did survive and here is what they think. The Lhiannon have constantly been cursed with bizarre and overpowering clan flaws which always struck me as an opportunity for a revision, with the latest official version from The Onyx Path giving them two. So when I picked up this file that was the first thing I went to. So their clan flaw is indeed changed but the writer opted for "extra aggravated damage from man made sources, such as guns and swords" without further explanation. This isn't any better in my opinion. This flaw essentially makes them even easier to kill and there fore even less reason for them to have survived. The ability to essentially read their auras easier wasn't a bad flaw and probably should have been kept in this treatment. I ran a Lhiannon in livestreamed game who had to essentially deal with this. But with the power of the Church fading and many of the older faiths coming under the microscope of dilettantes of that era, a Lhiannon in hiding could have hidden successfully within those social grey areas. So the idea behind this pdf is definitely viable but we aren't given any rhyme or reason how any of this happened.
Religion is briefly mentioned and their ability to rise in rank via prestige is mentioned but requires more than just the two lines it's given. At the end we are given three small plot hooks. The last two wind up talking about ideas that aren't mentioned anywhere else.
Ideas to fix this file: Expand on the history of the bloodline and the pivotal point in which they went into hiding. Expand on Ogham, what it is, how it works, other potential uses of the power, etc. Redefine the clan flaw as this is a game breaker. What happened to Dagda? She was one of the only Lhiannon ever printed and also listed as perhaps the only one left. As she was the childe of the Crone this would also be an opportunity to expand on that and her role (or hinderance) in the bloodline coming back. While this doesn't have to be 50+ pages, if it's going to be a 'clan book' it definitely needs more information to sink ones teeth into as it just isn't worth 4 dollars at this point. It would be better suited as a freebie or pay what you want.
