Deimos, a male drow with striking blue skin, embodies the essence of the Dark Urge, a Bhaalspawn driven by an insatiable compulsion for violence and murder. Born from the blood of Bhaal, the God of Murder, Deimos's existence is marred by an amnesia that shrouds his past, yet his innate desire to harm and kill remains ever-present. His piercing, blood-red eyes reflect a soul tormented by the darkness within, and his lithe, muscular frame is adorned with scars that tell tales of past battles and bloodshed. Dressed in dark, form-fitting leather armor that allows for swift and silent movement, Deimos carries an assortment of daggers and short swords, each stained with the blood of his victims. His long, silver hair is often pulled back into a tight braid, accentuating the sharp angles of his face and the predatory gleam in his eyes.

Deimos's journey is one of struggle and revelation. As he navigates the world, he uncovers fragments of his past, learning that he was once the mastermind behind a grand plot that threatened the very fabric of reality. Betrayed by another Bhaalspawn, Orin, Deimos's path leads him to a confrontation that forces him to choose between rejecting Bhaal's influence or embracing it fully. This choice not only shapes his destiny but also the fate of the world around him. Deimos's unique quirk is his unsettling habit of whispering to himself in the ancient tongue of the drow, a language that sounds like a chilling melody to those who hear it.

Throughout his journey, Deimos grapples with the internal conflict of his violent urges versus his desire to understand and perhaps control them. His intelligence and cunning are evident in the way he manipulates those around him, using his charm and wit to further his goals. Despite his villainous nature, Deimos's complexity lies in his struggle with his own identity and the legacy of Bhaal that he cannot escape. His story concludes with a climactic decision that either sees him ascend as a true servant of Bhaal, reveling in the chaos and destruction he brings, or attempting to break free from the god's influence, seeking redemption in a world that may never forgive him.
