Although Lux was created before the downfall of humanity, he was easily tossed aside by neglectful crafters and doomed to a few years of solitude in a stuffy attic, with his only source of light being the small window in the wall, his only joy the rainbow that came after the rain- and once humans had disappeared, he felt an odd sense of relief.

He kept himself locked up in the greatest libraries he could find in Elisium, absorbing every little bit of information he could and hardly ever leaving- at the cost of his social skills! Was it truly worth it, Lux? Eventually he moved on from memorizing the encyclopedias and dictionaries to...human fiction novels, and the feeling of yearning from doing so constantly ate at him until he finally found himself leaving the finest archives of Casea, desperate to see other Karurium and what's so great about having friends, anyways?

Lux is a somewhat naive soul, but that certainly doesn't stop him from being a bit annoying to be around- on account of him being just a tad uppity. He certainly has an ego, but is quite the gullible fellow, and is easily tricked by others (at the cost of his dignity). He believes honesty is the greatest and noblest virtue, and doesn't seem to catch on that others would ever go around and tell lies. Besides this, he's quite book smart and loves learning and teaching others, but his social skills are lacking and he can become easily embarrassed- despite his buried desires for companionship and affection.
