The Cradle Galaxy
The Cradle Galaxy, voted "the most boring place in the Omniverse" 13.5 billion years straight, is the ultimate safe zone in the universe where nothing bad ever happens. Well, some days it might rain slightly.
Whenever there's a crisis and danger lurks, if it's too much for your or your kids delicate constitution, the Cradle Galaxy is just for you!
There's an emergency door to it that's usuable by anyone ((except people actively seeking to evade plots they're in)).
