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 rebellion that’s been leading to Armageddon for thousands of years began with entities created before mankind, the cherubim, seraphim, malakim, Watchers, and other supernatural creatures we may not even be aware of. The Titans, the Watchers of the Bible, return when the angel with the key opens the pit. For those without the seal of God on their foreheads, it will literally be hell on earth.
