During the Ancient times the Xaliurians had planets called seed worlds, these seed worlds were Gravtite Nucleation sites where the gravtite Crystals would form into massive jets which can Cover the entire planet, one of these planets imploded sending Shards of Gravtite into a local nebula which created begun the creation of a new starsystem.
in Aetherians, Gravtite allows the gravitational manipulation to be controlled. as Aetherians can create a well of gravity which can create plasma in their hands which can be projected onto a surface. Aetherian breast milk is pink due to the fact that Gravity seeds into a young Aetherian's bone tissue allowing the formation of Crystals in certain bones such as femur, raddi, ulna, pecterian(Wing bones), and the finger bones.
