Luxus is was the goddess of Light of Kendesai, and one of the largest of the group next to Magmox. Shedding most of her form to ignite the sun, the tears she shed became opals, seeding even the darkest trenches of the planet's caverns with a glistening light. Towering though she may have been, the gold and silver form is merely a suit of armor made to keep her body stable after such a large expenditure of power.
Acting as the god of Ingenuity, she tried to find the answer to any problem that plagued her or those she cared for, and served as the inspiration for many of the more complex items created by the people of Kendesai. Though without those people, she would've lacked the suit to begin with, as she was unable to do much physical work without it. And it was those people that she showed only gratitude and hospitality when in her prime, defending them from the threat of demons, and teaching what would become the first demon hunters how to create weaponry that would harm the creatures.
However, one may notice that this write-up is past-tense. For while she was the first of the gods to regularly interact with the people of the planet, she was also the first to die. In a near-inexhaustable assault on the capital of the Light adepts, and finding herself still too weak to properly close any of the gateways, she formed a final, dangerous plan in conjunction with Aquatisk. Her and several chosen warriors would corral the demons as close to Luxus as possible... and she would proceed to breach her armor and cause a detonation strong enough to obliterate anything within the vicinity; Demon, mortal, or divine. It had a strange "cauterization" effect on the portals as well, causing them to close over with a strange "scar energy" that keeps them shut, but feels distressing to be near for anyone, living or dead. While the plan after that was to ensure her soul and those of the warriors were returned to the Divine Realm to recouperate... None of their souls were ever recovered. Not even that of Luxus.
