Armies gathered against Jesus - He brings them to Armageddon

 Dragon (Satan), the beast and false prophet gather their forces 

6th Angel vial - dries up Euphrates so kings of East can come

3 Evil spirits like frogs from Dragon, beast and false prophet summon kings

The 3 work miracles to convince kings to come

Ten kings - have one hour with the beast

Angel summons birds to get ready to feast on the defeated
