* They walked deep into the station to the inner side of the spherical structuring surrounding the future star to what looks like a series of 4 cannons emitting a beam of light toward the currently still liquid mass floating in the center. *
Ymir: This is one of the hundreds of beam platforms. The light is useless of course but the visual support is better for the show to visitors and it keeps people from clumsily walking in front of an activated beam. The gravity engineering team is at the console there, watching out to make sure their output is synchronized with the other platforms and don’t cause a feedback into the hydrogen flow still pouring in the center.
Yltel engineer: Actually despite the popular belief that our task is to increase the gravity of the star under construction to make sure it ignite, right now the gravity beams are working in reverse, lowering the gravity of the hydrogen already there. Matter create gravity by itself, that how natural physic works, but by lowering this gravity artificially we prevent the star from collapsing into nuclear reaction prematurely and turning out a dwarf.
