The question is, who or what is this star from Heaven? What is this key that he was given? We know that this is not a star like our sun. This star is a fallen angel. It may be Satan himself.
And he said unto them, I beheld Satan as lightning fall from heaven. Luke 10:18
This Abyss was created on the first day of creation. It will be this abyss that Satan will be cast into not more than 42 months from the opening of the Abyss. We see in the following verse that the angel that fell cannot hold onto the key.
And I saw an angel come down from heaven, having the key of the bottomless pit and a great chain in his hand. Revelation 20:1
2 And he opened the bottomless pit; and there arose a smoke out of the pit, as the smoke of a great furnace; and the sun and the air were darkened by reason of the smoke of the pit.
The earth has already been darkened by the dust in the air from the three impacts. As that clears, this bottomless pit opens up. The question is, what does this out look like today unopened? Could this be Yellowstone USA, Salma Caldera in Saudi Arabia or another one? Already we hear strange stories about people going missing in Yellowstone.
3-4 And there came out of the smoke locusts upon the earth: and unto them was given power, as the scorpions of the earth have power. And it was commanded them that they should not hurt the grass of the earth, neither any green thing, neither any tree; but only those men which have not the seal of Yahuah in their foreheads.
Some natural scorpion stings may cause paralysis, severe convulsions, cardiac irregularities, breathing difficulties, and death. The question is, how does the seal of Yahuah prevent stings from demonic scorpions? It's not a natural answer, it's spiritual in nature. Another question is, why are there still sealed people on Earth during the Great Tribulation?
5-6 And to them it was given that they should not kill them, but that they should be tormented five months: and their torment was as the torment of a scorpion, when he striketh a man. And in those days shall men seek death, and shall not find it; and shall desire to die, and death shall flee from them.
Scorpion stings effect your liver, heart, lungs and other organs. You may have problems swallowing.
7-10 And the shapes of the locusts were like unto horses prepared unto battle; and on their heads were as it were crowns like gold, and their faces were as the faces of men. And they had hair as the hair of women, and their teeth were as the teeth of lions. And they had breastplates, as it were breastplates of iron; and the sound of their wings was as the sound of chariots of many horses running to battle. And they had tails like unto scorpions, and there were stings in their tails: and their power was to hurt men five months.
Probably interdimensional genetically modified creatures that has been locked up in the Abyss from a previous Earth. Bu who knows.
11-12 And they had a king over them, which is the angel of the bottomless pit, whose name in the Hebrew tongue is Abaddon, but in the Greek tongue his name is Apollyon. One woe is past; and, behold, there come two woes more hereafter.
In English Abaddon is called the Destroyer. Another Masculine noun in Hebrew for Destroyer is Paris. In Jeremiah 7:11 Paris is translated robbers. Yahusha said something like this before they killed Him. There will be people thinking the Destroyer from the Abyss is their savior.
