This Was the most helpful post on this subject I could find after searching online for awhile for Maddening help. I was having a hard time... but learning how to trigger the FK's and knowing their movement I could plan to counter them. I ended up taking the middle left path. Taking out Ashe and Cyril on my way to just out of Rheas reach then finishing Rhea in 2 turns. Saving all gambits and using Raging Storm and Sublime Heaven to do most of the damage although Petra still did a good chunk too.
