, [the warning as not repeated] and~

The protagonist is riding to Amber.

His magical, invisible, sentient weapon, Frakir gives him a warning.


Frakir pulsed once, lightly on my wrist. But hell, that had often happened in traffic when I'd cut someone off. A hungry fox could have just passed, regarded me and wished itself a bear. Still, I waited longer than I had intended, prepared for an attack and trying not to appear so.

But nothing happened, the warning as not repeated and after a time I rode on.

I can't figure out either the meaning or structure of the underlined clause.

So I'd like to know the structure of it.
