Lava condenser

Small Story:
Originally there was no lava in the nether, an "alien" race with very advanced technologies arrived but the dimension was not habitable for them. So they built these structures for the whole dimension. These buildings took lava from other dimensions to bring it here, now there are very few structures left and they are out of control. This species, after millennia that inhabited the size, is demoted to the wild, in fact you can still find the specimens of the species, they are now called "Strider".
