Hi Keith,
Sadly, I have no idea. - I am getting the books via ebay, together with a load of other OOP RPGs from Spain. - Also, I was a bit estranged that the game has nearly no internet representation, not even in Spanish.
However, the Spanish Wikipedia article "
http://es.wikipedia.org/wiki/Aquelarre_(juego_de_rol)" [Just copy/paste it, then it will work.] suggests that the game is actually being published by the French company Crom. Ricard Ibanez is still into RPGs, but has focused on the
Alatriste RPG during the last few years.
But as with all RPGs, one can get them fairly cheap at ebay - if you're interested in the Spanish books, I can forward you the seller I am buying from.
Yours,
Rafael
