If it weren't for Sirion interference, Fontan would have probably been down to it's last region... Also that information you said about priests of Ibladesh, interesting information for Perdan don't ya think. 
Well, like I say, you can do whatever you want to do. After all, Westmoor is born from Perdan flesh, is it not? Perdan is your Mother land, surely Mother does not want see their child getting hurt.
Or you may even invent any evidence IC and show to Perdan/Caligus/Sirion for that matter. This has happened in previous wars and it will continue to happen in future wars.
Just Warrrrr...... Let the blood spillllll...... Let all realms take sidessssss.... Heh.
