An extremely solid translation of Arthurian lore to Scion. Could use more explicit character creations notes, especially about how to tie a Pendragon candidate to a Pantheon (or not).

My favourite Scion title since Mysteries of the World. The writeups on the pantheon and the mantles are especially good.

This is one of those cases where a star rating is very, very difficult to give, because it feels like Once and Future contains two different books.

One of them is a meticulously researched meditation on Arthuriana and a love letter to Welsh storytelling and culture, a beautiful fictionalized rendition of the characters of the Mabinogi, and a really quite clever reframing of Scion to accommodate the story of Arthur Pendragon within the existing mythic framework of the setting. It also contains some of the best and most useful Knacks the game has presented since release, with a lot of clever implementation of the Calling system that makes it a very good book for people with no interest in Y Plant Dôn (although you really should buy the book just for that writeup.)

The other is weak and paper-thin regurgitation of the most popular retellings of the story of King Arthur, possessing little originality and even less depth of research. An entire section is carved out for the Visitation of a character who is neither Welsh nor Arthurian, an awkward insert into the game's narrative that doesn't make the Appendix any more digestible and wastes wordcount on an unfunny con attendance bit that wears out its welcome faster than cheap running shoes. It's an Arthuriana that seems to have stopped at Geoffrey of Monmouth, leaving knights like Kay, Palamedes and Bedivere as bit characters and, in spite of citing the Green Knight as one of the sources for the pregenerated adventure, seems to have missed all the parts where Gawain is uncomfortable with a married woman flirting with him and learning his knightly virtues along the way, choosing instead to characterize him in a way closer to Mallory than any of the wealth of material treating him as a virtuous and respected knight. I feel this is a missed opportunity to diversify the Mantles available.

Ultimately, I think the really good outweights the parts I didn't enjoy enough that I still want to give the supplement its flowers, but there are definitely parts that detract from the experience as a whole that, for lack of a more granular way to express it through the star ratings, remains a part of the review that I hope will be helpful to others looking to pick up the book.

Fantastically written, wonderfully composed and masterfully presented, Once and Future is everything I could want both as a Scion player and a Storyteller. The knacks are flavourful, the Knight calling/player splat offers new ways to experience the world and the New pantheon, the Plant Don, is beutifully written. While I'm still digesting this book I an for sure say its one of the best the line has to offer. Cheer's to the people who worked on this masterpiece.

Faithful to the topic, well researched and explained, weaves the Arthurian myths well together with the system. One of my favorite Scion books so far.

What a fascinating brilliant book, My favorite sections are the ones written with playable content in mind

edit: here's more stuff about what i liked

The idea of mythical cycles is brilliant,more new ideas in scion please! more talk about mantles! more descriptions of the setting made by characters in the setting!

Love the advice on historical settings, the increased focus on mantles, and the new knacks.

The relics are a little wonkily priced and the Knight could use a bit of clarifying and maybe a slight retooling, but I’m hoping those will be fixed in errata. Otherwise, I’m a big fan of this book

An excellent supplement to Scion 2e, this book brings Arthurian Legend/the Matter of Britain and the Mabinogion to the World, and does so with an excellent blend of lore and mechanics. The new Plant Dôn Welsh Pantheon is great, and the new Knight of the Round Table Calling/Path is amazing too. We also finally get new Knacks for the eleven base Callings in Origin/Hero, mounted combat rules, and rules for taking up a fallen Mantle as a Demigod.

Once and Future is a worthwhile addition to one’s Scion Second Edition collection, and I recommend it in the highest possible terms,

Possibly the best Scion 2e book outside of the core hardbacks. Faithful to its topic and mechanically innovative at the same time.

The dots for the Relics are a bit wonky and hopefully it gets fixed in errata but this is a good product for anyone that wants to play an Arthurian Scion and the Knight calling and some of the rules for kingdoms can be used for any settings. Also props for admitting that some parts of a mythology are speculative or fabricated. It's good to admit it upfront as these things are very difficult to find records of if even complete records but it's also important not to spread fiction as historical fact or beliefs.

Very good. Looking forward to Scion: God.

Echoing what others have said, it's easily one of the best supplements so far. Amazing lore writing, cool knacks, great bestiary, the Knight path/calling, and a fascinating new pantheon.

Probably one of the best Scion supplements of this edition. Full of great worldbuilding, lots of plot ideas, a fantastic Welsh pantheon, a great bestiary, fantastic Knacks and Denizen options for the game. Definitely worth a buy.
