In Verge, it appears a consensus has been reached.
Nature shall have it's way.
Tasha and some workers after recognising the waterfall will be left to it's own devices, claim the nice big table and it's cloth and candle. As well as the stone flagstones and benches. Thorvven shakes his fist good naturedly at her and shouts "Once a thief, always a thief!" and she uncharacteristically flushes and throws a rock at him. Which indeed starts a Tavern versus Tavern heckling contest across the way as more water spills out of the bubbling underground stream. Almost looks mineraly, steamy. Hmmm.
The heckling turns into a drinking and carousing evening by torchlight and candlelight as dancing fireflies and steam float up to the sky.
"We await the rocks to break and fall..." are some of the wild drunken chants.
But if the earth ends in fire And the seas are frozen in time There'll be just one survivor The memories of our lifetime
