Tenebourous appears as a handsome horned devil with an obsidian black hide and veins of deep red coursing across his body. His eyes radiate an eerie, cold blue flame that seems to pierce through the very soul. Massive, twisted horns encircle his head, tipped with silver and crackling with dark energy.
Large, jagged-edged wings extend from Tenebourous' back, casting an ominous glow. His long tail ends in a dark metal barb intricately etched with runes that seem to writhe and shift as if alive. Custom-forged, blackened armor adorns his frame, each piece inscribed with runes of torment and suffering. In his hands, Tenebourous wields a dark metal fork decorated with infernal symbols. Shadows cling to him as if drawn by some unseen force, and an aura of dread surrounds him, a constant reminder of the dark power he wields and the dire consequences of those who dare to strike a bargain with him.The origins of Tenebourous are shrouded in secrecy and myth, with countless tales and legends surrounding his existence. Some say he was once a mortal who struck a bargain with an arch demon, while others claim he is a primal embodiment of the shadows themselves. Whatever his true origins may be, Tenebourous has persisted through the ages, forging cryptic contracts with mortals who dare to seek his boons.
With a keen understanding of the desires and fears drive mortals, Tenebourous offers them seemingly benevolent deals, only to exact a terrible price in the end. Those who enter into contracts with him often find themselves granted great power or protection, but with a hidden catch that ultimately serves to further Tenebourous' goals. As the centuries passed, Tenebourous continues to weave his intricate web of alliances and agreements, slowly amassing power and influence as he manipulated the lives of mortals to suit his purposes. A knight granted victory in battle here, A king granted a noble heir there. Sometimes the price exacted immediately, and others paid in the future willingly or not. It seemed for eons that Tenebourus' wit and cunning would serve him unending, until a group of adventurers would catch his eye. He would offer the knight a trade. in exchange for taking on all of the pain and suffering the knight may endure, he would have the man serve him for 20,000 years after his death. What Tenebourus didn't mention is that although he would take away the pain, the damage would remain. The knight fell to his injuries after the very next battle. When Tenebourus appeared to take the soul he was promised the mage of the party noticed him, and for the first time in his life Tenebourus felt uneasy. Met with rage as intense as the world star, Tenebours was forced into a trinket where he would spend the rest of his days, Reliant on hapless passerby's to sign the contract of the ring to survive. The ring became known as the Mourners Ring, for it would claim the life of those who wore it after they were assured victory in battle. it exchanged many hands until it was lost in a war with the fey.Tenebourus first appeared when Matanza lifted the curse on Slender's ring. He appeared and killed the bard immediately, causing Jadeth to run off and collect the rest of the party and prepare for a fight. The fight ended with Tenebourus returning to his ring prison, and the problem was solved for the moment.
The morkoth, Thalazar, freed Tenebourus from his ring again, and he proceeded to engage the party in combat once more. As his health lowered, he pinned Jadeth against the wall and promised to slay the Godslayer heiress for what her uncle had done. Jadeth warned Tenebourus that Alastor was no friend of hers, and Shade offered his soul in exchange for some power. Tenebourus took the deal with Shade, and plotted his ring trap revenge on Argos.
