The Hourglass

Well, I got a question if you can create any alternate universe or timeline of a MK universe, what will it be?

I know you can shape destiny and all that with the hourglass. But is it like when you shape a new timeline, like you're creating a new alternative universe or something? I just wanna know if I had the hourglass. I'm creating a new universe or something! Please, 100% simple answers.

Also, shaping the characters of the new timeliness or alternate universe if I'm right or wrong!

If you were the Keeper of Time. What Era would you make?

At the end of MK1, we see Raiden, Kung Lao and Kitana as Keeper of Time, but in their respective timelines. It is said that when Liu Kang faced Shang Tsung in Aftermath, several timelines were created during the battle, with each different character gaining control of the Hourglass. That is, are all endings canonical?
