Sleep magic!

Makel's dimension seems willing to do anything at all as long as every single moment is from every single angle a good shot in a music video. He spends a while exploring and expanding it. He can fly even in the parts where gravity would be incompatible with that, once he's had some practice. 

That is just awesome!

And Flying is the best.

Next?

"I'll go!"

Cool. They go through the motions. Sleep. Shard. Portal.

Kantil's dimension has a harbor and a port and then nice flat neatly graded neatly surveyed land all ready for him to sell to whoever wants to develop there. He is so pleased with it! It's perfect!!

Dana has a giggle fit over this. It is perfect.

"Can the avatar I manifest while sleeping leave my dimension?"

"Not at all. And not even everyone manages to make an avatar consistently either. If the avatar-you tries to leave the bits that go through the portal just don't exist outside."

"Then I think I might practice making an avatar consistently and presuming I can do it make my university relocate to inside my dimension so I can be asleep all the time."

Giggle. "Your real body still needs to eat and exercise. But good luck."

"I hear magic healing is a thing that exists?"

"It's not a thing that currently exists in this universe."

"Okay, okay, I will be cautious with my body until someone invents it."

"Wish you the best of luck in your new found productivity."

Next?

He is at last satisfied with his Russian.

(She is glad!)

And what do we get from Afen's dimension?

Four suns in the sky, and the planet appears to have rings, and there's a wood-paneled winding hallway with one side dominated by computer screens and the other side largely open to nature. Cold and snowy, here, with flakes blowing all around but not onto the wood or into the hallway. Ten meters down it's a desert. Ten meters past that, a thin atmosphere and a dusty lifeless surface, weak gravity. A forest. The pressurized surface of a gas giant. A miniature cityscape. An active volcano.

This feels very interesting to his weather sense. He flies down the hallway. Any sign of Afen?

Walking gleefully down his hallway!

"Hey, you! Your family produces some really interesting places."

"Of course we do!"

Giggle. "Wanna comeback and see the exciting new things your dimensions does?"
