Breaking arms and cutting off fingers are her stock-in-trade. Finding life under his rule increasingly unbearable, Katsa forms an underground Council whose purpose is to combat the destructive behaviour of the seven kings - after all, the Middluns is only one of the Seven Kingdoms, each of them ruled by their own king and his personal agenda for power.
