I'm so lost. Why are they fighting Carlos? I thought everyone was friends...

Lol true

Isn’t it to help limon look better in his father’s eyes, like Iirc inferna was the one who contracted carlos

it didnt sound like they agreed to help, more like theyre getting involved in the war in an attempt to gain control of the dragon slayer spear, without regard of who takes the throne of the golden empire in the end

true. everyone else just doesnt want their dragon to die or be taken away. so spear is more of a priority.
