They're not the fighting type, they only want to talk with you. And they will simply kill you if you're reticent to conversion. If you want to survive, you have to burn the rope before the entities score two eruptions.

     When the first of them erupts, the last one erupts too, but there is only one eruption. You may ask : who erupts? The volcano is a huge maze inside. The big green dragon is flying above you! It will try to convert you, but it will first allow you to ask for one wish. I have to warn you : it has to be a passive wish.
