The Antichrist comes from the bottomless pit. Certain creatures are assigned to this place. Satan will spend the 1000 years not in hell, but this pit. In Gen. 1.2, the abyss or the deep is also the pit.
Tartarus in Homer's Iliad is the lowest place you can possibly get as low as earth is to heaven. Therefore, we can deem Tarturs to be the bottomless pit, after all the pit is bottomless and you can't get any lower than that.
