We don't get an article instead Mark Rosewater (head of all un-magic) and Ari Zirulnik (creative member who worked on Unfinity) did an episode of drive to work talking on the legends and made it canon to the un-verse;
I have written up a summary of what they said but I suggest listening to the podcast as I'm just kinda doing a wiki version of what was said. I did this also as with everything going on I thought this would be a fun set to look at and add too.
Myra the Magnificent's Intergalactic Astrotorium of Fun;
Myra the Magnificent and her Intergalactic Astrotorium of Fun
Myra's goal in life is to make the best park she can and entertain people. She loves and respects her employees who help her and always tries to find the perfect place for those she works for where their skills and passion can shine most, such as having the vampires run the midway. From a young age Myra inherited a huge falling apart space station and saw this as the chance to leave her mark on the world.
Myra's main goal is to entertain and make a fun time for people and kinda will do whatever she can to do it, often saying “Safety 12th”. Due to this a lot of the park’s technology is barely held together and is always needing repairs. Myra will often try to cut costs in any way she can, such as making the zoo a petting zoo to cut costs on cages or removing the backs of chairs since the crowds are on the edge of their seats anyways. The park is also infested with multiple types of vermin; squirrels, rats, beebles and gremlins. Each predates on each other (space squirrels can take down a beeble in a blink!) making a kinda stasis between them.
The three main creature types classes of the park are;
Guest - those who come to park to enjoy.
Performer- any of the people who are part of the acts in the park.
Employee - Everyone else who works at the park.
Truss, Chief Engineer
Truss was a hacker who once hacked the park for fun and when Myra found out she offed Tuss a job there. Much of her day is taken up by other employees calling about a problem happening or something going wrong. As this happens so often she just hacks something togethers to fix the problem for a moment instead of full fixing it. She has an assistant named Glaxxar who she sometimes mistreats out of neglect, lost in whatever other task she needs to do.
Pietra, Crafter of Clowns
Pietra Honkhonk McGiggles is the creator and builder (vai the Mirthing Pod) of all the robots in the park and is the only human clown. A brilliant artificer, goofball and someone who takes comedy and joke crafting very seriously, she found a way to mix her two passions by making robot clowns. She aims to make the best clown robot ever.
Captain Rex Nebula
Greatest pilot in the universe…oh so he says and more likely the cheapest one Myra could find. While he is great at flying smaller ships he isn't the best driver when it comes to bigger space ships, like the Astrotorium. In fact he was the one who destroyed the home planet of the Blorbians, Blorb-12 when he backed up into the planet.
Ambassador Blorpityblorpboop and Blorbs (Aliens)
The Blorbians now live at the park after Myra gave them lifetime passes after their planet was destroyed. As such they are the masters of the park games and you might as well give up if your going against one in the games.
They are led by Ambassador Blorpityblorpboop since the former rulers didn’t make it through the crash. Lacking anything official, he declared himself as the ambassador and to shut him up everyone went with it. He’s really not over the trauma crash but he has formed a friendship with Rex and the two will sometimes get dinner and have friendly trash talk. His ship is full of all his game prizes.
Devil K. Nevil
Devil Kdanger Nevil (the K is silent) is the star daredevil, and a literal devil, of the park. He's broken every bone multiple times, has been set on fire many times and nearly anything bad that might have happened has happened. Despite all of this he never wavered in his euphemism for performing. He feels the most alive and happy in the middle of his stunts and happy risks the many dangers that could (and have) happen.
Monoxa, Midway Manager
While Truss helps Myra with all the technological needs, Monoxa was hired by Myra to be the people's person, though she can be a bit cold blooded as vampires tend to be. She is in charge of keeping track of other employees and helping guests with any issues. She is very good at the job (and knows it), having worked her way up to her current position. She will do what needs to get the job done, even secretly teaming up with the rats of the park
Roxi, Publicist to the Stars
Not saying which Stars, Roxi was brought in by Myra to help with PR such as dropping of flyers on planets to make sure everyone knows about the Astrotorium.
Tusk and Whiskers
Tusk and Whiskers were hired as separate acts but often Myra will toss multiple acts together when low on time or money. The two found that they worked together great and now the number one act of the park (barely edging out Harold and Devil). Tusk is the Elephant and dislikes peanuts (as well as the stereotype) but loves cashews and Whiskers is the mouse and has a normal sized pet dog.
The spinner of the safety nets at the park and she loves her job as it lets her always getting her food delivered. Like other animals and non-humanoids of the park, Spinnerette willingly works for Myra (who pays her in food) and only does things she is willing to do and never forced into anything she isn't willing to do.
Comet, Stellar Pup
Comet is a good boy!
Comet is just a dog, not a dog person, not an intelligent dog, just a dog who just happens to be a planeswalker after an unknown traumatic event. Despite this he enjoys life as a planeswalker, able to dig up bones on Innistrad to bury on Zendikar. Comet doesn't really keep a thought in his head for more than 10 seconds. His main goals are just to eat, dig up bones, chase squirrels and just have fun. He found the park one day and it has become his new home. Myra having grown found of Comet, built him a dog house ship to rest in in-between his multiverse adventures. He also never gets bored spending time in the park chasing squirrels as space squirrels are his favorite to chase.
