"Bear witness to the agent of your demise."
Sithis, also called the Grim Reaper, or even Death, is the Dark god of Death, Fear, Despair, or any kind of emotional suffering. Sithis often takes on the form of a dread skeleton with bony wings, wrapped in a dark blue robe with a hood that hides his entire head. He wields a scythe known as the Ender, which is rumored to slice the soul out of every mortal who passes into the next life. Sithis, along with Ares and Haagen Dasz, is one of the most powerful Darks apart from Aku. This is because of the constant cycle of death occurring in Existence, especially from War.
Sithis is silent and mysterious, and he rarely speaks. He cares little for the fleeting existence of mortals, and he only cares about bringing his own ends to fruition, and harvesting unfortunate souls, hoarding them away and bolstering his own power. It is believed that Sithis does not actually hold any loyalty to Aku, and instead serves him out of convenience.
Sithis is one of the most sinister Dark Gods, constantly scheming and planning. He is the creator of the so called "Curse of Sithis", which is rumored to resurrect the corpses of the dead, as mindless killing machines bent on slaying the living. He also created the Lich King, and the Scourge. He is one of the most dreaded gods, and trusted by no one.
