The identity of Abaddon and Apollyon in Revelation 9:11, the angel of the bottomless pit, is Saturn—the Watcher chief Shemihazah. The opening of the bottomless pit marks his literal return to earth. Saturn’s Golden Age may last only five months—the time he and his colleagues are allowed to torment humanity. It’s possible Saturn/Shemihazah knows this and doesn’t care.
The long war by the Fallen against their Creator is for control of God’s har môʿēd, His mount of assembly, Zion. That’s His prize jewel, and that’s why Saturn wants it. Armageddon is the battle for control of the har môʿēd—Zion, God’s mount of assembly. The final conflict of the age will be fought at Jerusalem.
