Here is mine.
SubRosa 14 follows the exciting SubRosa #13 which covered Diedne house quite vastly. It sets up a peak of information, because it was HUGE. The issue #13 is like the stepstone with which all new SubRosa will be compared, considering length, content, accuracy.
Let's the game begin! (but of course, with kindness and fun, because it's a funzine)
From the line editor : David talks about Transforming Mythic Europe. I haven't this book yet, waiting for many books to be published by Atlas to do a grouped buying on the american amazon website which cost so much with transport fee to Europe. At the question "why no magi changed Europe before 1220", I think that his answer is quite a lot similar to "why haven't magi do more breakthrough in the game". I expected a plain "because there would be no place for PCs to be the one doing it, which is quite the purpose of the game" but it was a bit more elaborated than that.
The storyguide's handbook : as usual since a few issues, give us tips to create adventures. This time, we are introduced to the mindmapping process. I knew that from work, where there had been quite an emphasis on it, because it's "à la mode" or trendy. Personaly I tried to use it, but it was hard, because I know that my PCs will never really have the same ideas confronted to a situation than me. So I'm using a lot of time to try to figure which thing they would go for... often needing a non-linear mindmapping, which are often quite complexe and quickly. I haven't downloaded any of the programs proposed, and used only my pen&paper tool. But it was interesting. I think that article is something you have to read, try, reread, retry, etc. only to stop reading it when you are quite experienced with it. Links to free (or not) softwares are included, which is not bad. A meta-analyses of your mindmap form is also included, which is really interesting.
Verditius longevity devices : this chapter will try to gather 2 ideas which, at firest, are contradictory: the house verditius, and the desire to prolonge life. I doubt(ed) that those two may be put together, since items are maybe the least of the thing I consider leading to a longer life, but well. We all know the lich thing and I gave the chapter a try. There was a part on the phylactery, which was thematic. Second was a mystery of Credne. I read it but I didn't like the theme. I found that we were going to the cyborg part of the game, and my Mythic Europe is not that way. Plus, I think the airgetlam brings too much maths. I think that I would perhaps use the phylactery mystery, but not this one.
Demography of the Order of hermès : this is a subject which is highly debatted in my troupe. Me and my ASG are not at all of the same opinion, and I read this article with interest since I'm convinced that any source of information is quite useful to counter his arguments. Looking at the past and to the future, there are sharts, and explanations of the considerations used to create those. I think this is one of the article I will use the most because it is something of "metaknowledge of the game" which you are always using, consciently or not.
From the journal àf Vulcanis Argens : well, like previously: information, ideas of stories, under the form of a journal. Each reader like this or that, or all or nothing. But the concept don't change much.
An eternal love : an old adventure by Jérome Darmont. I already used it before, so when I read it, it was nothing new, just adapted. The story includes principaly elements of meddling with mundanes, and relation to nobles. There are no magical battle, but rather subtle interactions. Combat magi not required.
Mythic bloodlines: more than the founders. Interesting article. It provides fact and information about some well known folklore persons and creatures, from which the magi could be descending. Useful for those magi who are using mythic blood.
Companion piece: the three good men of breifne : like always, this companion piece give us companions ready to play, with background and characteristics. IIRC, every previous time, it was linked to the recently published book. This time, it's related to the hibernian tribunal, covered by the Contested Isle. Seen their background, I personaly would not use them if not in their normal ground.
The first lineage : the inventers. The author (mark baker) is writing about Bonisagus lineage. Since Bonisagus is a true lineage, it's quite important in the in-game universe to know. If a player ask you a question about the first Bonisagi, you have answers ready. The bonisagi presented have some characteristics and virtues and flaws of note. Their area of expertise, quote or interesting features are given, to enhance their credibility. I liked the Sepentia Bonisagus theme. What a cold blooded researcher!
Something I believed would be there but wasn't, was the article from the view of Diedne by Naomi Rivkis. But reading those pages of SubRosa again, I misread, and it was never intended to be "in the future issue of Sub Rosa" but rather "in a future...". Argh!
So to conclude. I liked 2 metagaming articles (demography and mindmappin); I will probably use 2 others (Bonisagus and Phylactery mystery). If I ever need a mythic blood idea, I know I can find lot of thematic ones here, and in case of question about Bonisagus background, I'll just be sure to reread the last article.
