Tartarus and The Anti-Christ

In classic mythology, below Uranus (sky), Gaia (earth), and Pontus (sea) is Tartarus, or Tartaros (Greek Τάρταρος, deep place). It is a deep, gloomy place, a pit, or an abyss used as a dungeon of torment and suffering that resides beneath the underworld. In the Gorgias, Plato (c. 400 BC) wrote that souls were judged after death and those who received punishment were sent to Tartarus.

Like other primal entities (such as the earth and time), Tartarus is also a primordial force or deity.

In Greek mythology, Tartarus is both a deity and a place in the underworld even lower than Hades. In ancient Orphic sources and in the mystery schools, Tartarus is also the unbounded first-existing entity from which the Light and the cosmos are born.

In the Greek poet Hesiod's Theogony, c. 700 BC, the deity Tartarus was the third force to manifest in the yawning void of Chaos.

As for the place, Hesiod asserts that a bronze anvil falling from heaven would fall 9 days before it reached the Earth. The anvil would take nine more days to fall from Earth to Tartarus. In The Iliad (c. 700), Zeus asserts that Tartarus is "as far beneath Hades as heaven is high above the earth." It is one of the primordial objects that sprung from Chaos, along with Gaia (Earth) and Eros (desire).

so ive made tartarus a titan who rules the pits beneath the under world, though he was put there as severe punishment,
hence the name "the pits of Tartarus" or just Tartarus like Hades named after its ruler.

And the Unholiest of all, the Beast, the Antichrist

there are three beasts, which form the unholly trinity, the antichrist speaks in the tounge of a dragon and therfore he is not understood by mortals, yet the secound beast can translate and so the first beast speacks through the second, its very confusing, im not quite sure which beast is which, so i could be wrong
