The Tattered Banner

I read this before. Or most of it. I can’t remember when, but it must have been long enough to go that plenty was surprise to me, though not the broad strokes.

A young man is preternaturally talented with the sword. Or supernaturally talented. This fantasy world is mostly magic free after similarly talented swordsmen (whose talent was nearly or perhaps actively magical) rose against wizards.

The hero is reasonably charming, but a little vague in his depiction. The story is of the young man being guided into accidentally setting in place conditions for a coup, after which he must flee the are and the book ends. I gather there are sequels.
