The water in that fountain makes you ten years younger, and drowning is completely normal ; you can easily start by being silent too. And then, speak to her very nicely. She'll "listen" to you in her own mystical way. Then if she considers your request worthy of it, she'll send her army of old greek writers. 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. Since all intermediate eruptors are usually checked out by the mayor, you have no choice but to revert the first crater to its previous revision.
