There was a trilogy I read in 8th grade that I really, really loved, but I can't remember the name, the author, or the names of any of the characters.

The books were centered around a couple small groups of people that fought in and led a war. They were fantasy books, and the setting was pre-modern, but it wasn't Earth. The organizations in the books had an Italian mob sort of feel.

The only complete memory I have from the books is that one of the characters gets knocked out and wakes up in a sewer in a city.

Anybody have any idea what these books might have been?

What is it they say about silence being golden?
