Volume 1 is only "very difficult" to find.  The others are "extremely difficult" to find.  I only know of maybe 3 copies of these books around.  They have been on my want list for a long time now too.

I read the reviews in "Space gamer" and in "White dwarf", but they tell us little about the magic system.

The one contained in "Space gamer" says that it is pretty innovative, and that both (magic and combat system) are quite complex.

So, apart from the few sentences we can found at rpg.net here:

most of us really don't know anything about this topic.

A piece  of fantasy RPG history lost forever? Sadly, it might be.
