George Martin. A dance with dragons (№ 446386)

We have made peace with the Brackens a hundred times and sealed it many times with marriage alliances. Every Blackwood has Bracken blood, and every Bracken has Blackwood blood. Under the Old King, peace lasted fifty years. Then some new quarrel broke out, old wounds opened up and began to bleed again. My father says that's how it always happens. As long as people remember the evil done to their ancestors, no peace will last long.
