ok, also, if it was lava..then why did nothing else burn in the area surrounding. If it just happens to be lava, then it would have burnt all the wood in there and carpet. Also, the not done wool was destroyed, yes that can burn but it would have reached all the letters, burn those completely and burn most of the world in that area too. Even if it did rain, the lava would have started burning the wood again looking at how close it was to the wood it did not burn. the sea lanterns where also placed 14 wide from the center out till it hit a portal or wall. You can see that there was blocks broken in between other lanterns. Also that curve shows someone used tnt in those spots and blew up that area. The blast are is not too bad for a c4 or a lightning strike blast. That was either someone using there fist to destroy the blocks or tnt, not a burning material
There was an old design with curves but i redid all the flooring due to lighting issues. I undid 2 carpet and replaced abut 2,000 blocks of it. I know the lanterns where in plus shaped when i did it.
