As I said, if the Fairies attacked the Markavian, it was not a war, but a slaughter, the Markavian couldn't nor would try to mount an effective resistance, messages take months to arrive between groups. Plus their magic has very little combat applications.So yeah, are Fairies genocidal?
It's more that Cats quite literally preyed on innocent Fairies, and they responded with deadly, organized force.
