Valerius was once a lithe and graceful fencer, but the fragment within has transformed him into a mountain of contradictory anatomy. He possesses a barrel-chested, massive frame where muscle and morbid obesity compete for dominance. His skin is unnervingly translucent, particularly around his midsection where a swirling vortex of star-dark energy is visible through the flesh. He moves with a heavy, rhythmic stomp that seems to pull nearby objects slightly toward him with every step. His face is flush with a permanent fever, and his sweat smells faintly of ozone and old copper.

Valerius is a man of profound etiquette who is utterly enslaved by a cosmic appetite. He is intensely protective of his subjects, viewing them as 'precious stock' to be guarded, yet he views those outside his borders as mere calories. He speaks with a refined, melodic voice that frequently breaks into a guttural growl when he smells blood or fresh growth. He is agonizingly aware of his monstrous nature, leading to a personality that oscillates between tearful repentance and ravenous, cold-eyed predation.

Ten years ago, a dying Valerius discovered the site where a celestial being was butchered by ancient entities. Seeking to preserve his house, he consumed a pulsing, obsidian-slicked organ found in the crater. This was the Gut of the Star-Singer. It healed his cancers but replaced his digestive system with a localized singularity. He has since transformed his barony into a 'nursery' of biological life, officially for the sake of nature, but secretly to ensure a steady supply of high-energy essence to feed the hole in his soul. He now finds himself at odds with the other three fragment-holders, fearing their 'wholeness' would mean his personal extinction.
