The most important thing for us to understand is that all that takes place is under the control of our God. He tells the angels to blow their trumpets, and they blow (9:1). He gives Satan “the key to the shaft of the abyss” (v. 1). He tells the demons what they can do (v. 4). He puts a limit on the torment they can inflict (v. 5). The fifth angel blew, and John saw a star that had fallen from heaven to the earth. “Had fallen” is a perfect tense participle
Revelation 9:1–5
