Hard Light Sentients
Hard Light Sentients (alternativly Hard Light Constructs, or HLCs)are meant to fill a role somewhat like the deities of the D&D world.
They exist either as A.I.s or possibly as uploaded consciousnesses stored on crystal data storage, but they have access to advanced hard light generators, allowing them to take physical form of their choosing. They can also create objects and some structures using these generators. On established outposts, their networks can sprawl across entire planets.
HLCs might even award special modules to players that will allow them to project hard-light constructs.
