All the years I regarded our Spanish friends with great envy:
They have the AQUELARRE - RPG.
But we can rejoice, there is now a Kickstarter for the English edition.
For me, this is the next best thing to an Iberian Tribunal book.
Aquelarre is the Spanish Ars Magica.
It is this kickstarter?
Looks like a different system, but also appears to be easy enough to adapt.
On the other hand, I really enjoyed Tribunals of Hermes: Iberia.
I'm currently on the fence about supporting this. Convince me.
Aquelarre is Ars Magica without the Order of Hermes, set in a gritty Medieval Iberia full of magic, demons, faeries and all the shades of human wickedness. It is also a bit darker than 5th Edition Ars, but it is an awesome game. The system is classic D100 (Cthulhu, RQ…) with some tweaks.
Also, all the books of the line look awesome. You can check it with these sample pages from the last book in Spanish, Bestiarum Hispaniae: http://www.nosolorol.com/pageflip5/index.php?id=AQ012&utm_content=buffer90e6f&utm_medium=social&utm_source=plus.google.com&utm_campaign=buffer#demo1/page/1
I really think that any Ars fan will love Aquelarre.
The magic in Aquelarre is based in real medieval grimoires.
At the very least, this book would be a huge bump in source material to flesh out the Sorginak of Iberia and the Pyrenees, as well as the history of the area.
-Ben.
