Tavakanax is the most essentialistic looking god, for he is permanently put into the form of a large inky mass. His sister carries her golden chalice, in some of his humanoid depictions the Dark Void carries a dark brown glass bottle full of a liquor that looks like ink. It was from this liquor that transformed the human form of Tavakanax into the Dark Void. He is the physical embodiment of evil and chaos, he was twisted into the opposite of his sister someone who takes rather than gives just because he wants to. He became crazed and turned into the catalyst for the War of the Gods, the whole reason that the war caused a new era.
The Dark Void was a small Ghostwise Halfling man, his face was scarred since he was born. His hair was long and dark, nowhere near as long as his sisters, but still long and near black. He would wear basic brown clothing and other earthy tones, but ever since he became warped he's a different "person". He is a seven to eight-foot-tall shadowy form that drips ink and darkness, the same ink and darkness that drips from the Omniscient's wound.
