Taleweaver's Tent of Wonder

You conjure a tent that leads to an extra-dimensional space. When you summon the tent it can be whatever size you want as long as it fits into a 20ft cube. You can have an entrance on any and all sides of the tent. Only people you designate when you cast the spell can see and enter the tent. Inside the tent there are 3 different sections, the Stands, the Stage, and Backstage. Also, inside the tent, other creatures are categorized into two different designations, Crowd Members and Performers. You choose for each creature when they enter the tent. You and any Performers may teleport to any unoccupied space inside the tent as a bonus action. You may stop Performers from going to any place you designate and can choose for specific Performers as well. The tents height on the inside is as high as you dictate and you may change it at any time.

Stands: When someone designated as a Crowd Member enters the tent they are sent here and can’t go anywhere else. In the stands violent actions are suppressed. If someone tries to make an attack roll or cast a spell with malicious intent, then they must roll a Wisdom Save against your spell save DC. On a fail, they don’t make the attack and they lose the spell slot if they used one. On a success, they attack or spell does go through, but any Save is made with Advantage and any damage is halved. A creature forced to make this save is marked with a pink aura that looks like cotton candy. Performers are immune to this effect if they are only affecting creatures that have been marked by this spell. You are always immune to this effect and can banish any marked creatures. When banished, the creature is sent back to the original plane you cast the spell in and is within 5ft of the tent or the closest unoccupied space. A creature banished this way may not enter the tent again until you cast the spell again.

When sitting in the seats, the creature’s vision is pulled into the action of what’s happening on the Stage, even when looking around it looks like they are in the action. If a creature takes time to look around, it does notice that they are still sitting where they were, but as a faint image.

Stage: The Stage is flat ground that is surrounded by the Stands. The size of the Stage is whatever you want it to be as long as it doesn’t go past the limit. The maximum size is 200,00 square ft. You can, as an action, change the size of the Stage as long as it doesn’t exceed the size limit. 

You and any Performer while on stage my change their appearance as if using the Disguise Self  spell as a free action.

While you or any Performer are on the Stage, that creature can create any scenery, creature, or object. Anything created from this effect feels real, but it’s impossible for it to damage a creature. Creatures created by this effect act however the person who created them decides for them to act. Food can be created and will fill any creature that eats it. Anything taken from the Stage disappears into a puff of smoke if taken off the Stage. You can cancel or override anything created by a Performer and you can designate areas that can only be affected by specific Performers. 

Backstage: You and any Performers are sent here when entering the tent. The Backstage is a small area with a snack table that has an assortment of snacks that are the favorite snacks of all Performers at that time. There are also endless cups of water on the table. There are also full body mirrors, 1 for every Performer. From here there is a hallway that leads to the Stage. From here you can see everything that is going on on the stage.
