Hey @Jeffrotheswell, @Xanotos said you might have contact with Shadox.
I'd like to have test some ideas with water and lava and I'd like to take some from a aqua/lava duct (see image below) of Shadox plot.
I'd remove the plot after a couple of days after testing too.
@james People also point out that a dev can give a water/lava source block. How does it work? I need to have a defined location and devs place the block?
