Well after further reading of the book I have to give a thumbs up to John Post's comments. He is right.
I think I was searching for something that is just not what the book is about. Subconsciusly I expected this to be a "pre-OoH magic" book. A book about the traditions that the Founders derived from. This is not such a book. Mercere was not a nautral magician, and Flambeau and Guernicus were not elementalists as I fist assumed,
They were something else. Probably related, but something else none the less. As such my firs t impression of the book was positive (I liked most of what I read) but did not fit well with my expectations. That is a problem of mine, not of the book itself.
Some of the material here can be used in a pre-OoH campaign, since the power level of the magi there is probably more in line with what you would find in smaller and less coordinated traditions but they will not be the bulldozers that a group of eager magi can be if they want. They can be powerful, but less all-conquering that the current members of the Order.
So I am changing my point of view here
Once I reread the book and finish the 2 chapters I have left I will remake my review.
I am happy to have changed my point of view since now I am more comfortable reading the book.
Cheers,
Xavi
PD: reading the saxon chronicles of Bernard Cornwell is a BAD THING for you if you were NOT planning to build a 800-900 saga and you just read the vitkir andf gruagachan chapters....
