Normally, angels didn't meddle with each other's worlds. After receiving a world, they took care of it until the end of times. One of the oldest angels Savine knew, Elder Evitanius, he held a thousand worlds under his supervision.
Every two days in heaven, he would visit one of them and make sure everything was ok. He spent a year or two there and would come back. After that, he would go to another world.
By the time he came back to the same world twice, two thousand years would've passed in that world. Long enough for the people to forget about him. Evitanius mentioned that he'd expect the people of the worlds he visited multiple times to remember him, but such occurrences were rare.
But regardless, Savine wouldn't be that surprised if an angel came here in the ancient times. Though, she couldn't recognize the name, Khalul.
