The sad truth that Feuriah refuses to understand is that if Eon did offer help, it wouldn’t have stopped the Fall. No amount of Skylanders could have stopped what Malefor had set up, if anything they could have possibly helped some Kuros escape/survive the mysterious collapse of the catacombs (the escape tunnels Feuriah tried to lead her own band of survivors but failed, leaving her the sole survivor). Or, they could have died in the collapse too, leaving Eon with little Skylanders left and Feuriah still alone. Sadly, Feur’s eggs had already been smashed before she arrived, and Voteil had already been killed.
Though, it possibly could have stopped Feuriah from turning against Eon. The mere notion he still tried and lost so much to help her, despite being the Queen of the Kuros, she possibly would have forged some sort of alliance to help defend Skylands, train recruits, all while attempting to salvage Kurosia in some way (or, have revenge). Now there’s an interesting AU 
But it’s one of the few truths Feuriah refuses to truly think upon. She’d rather have someone else to share blame for her people’s slaughter, to have someone to hate and fight against than to face the truth. She’s still convinced Voteil is alive and escaped than admit he died in the Fall, but refuses to speak about him or even accept the possibility of his death. She may seem like she has a lot back together in blog canon now, but she’s still a very, very broken dragon with delusions that most go along with for her mental sake.
