Upon appearing in an unknown dimension, Winder looks around to see if he has arrived at his desired location, or at least one of about a million possible desired locations. Though shortly, a Giratina with silver instead of gold and blades for wings, appears nearby.

"A visitor. How unexpected, I do not encounter a dimension-jumper that often. Especially not any dragons..."
"I am here to propose something, and this is one of few dimensions capable of hosting what I desire."

After listening to Winder's goal for a dimensional event, a tournament in fact, Alma had decided to help and offered up her own relatively empty dimension for the event where the pair were located.
She states her plans to gather pieces of worlds in dimensions where said world is about to be destroyed, so that it would not be missed. And also gather champions to take part in this event.

Winder, somewhat reluctantly, agrees. Only because this is her world that he entered and is hosting this tournament in. And furthermore, he still needs her assistance for this on way or another.
But before letting her depart to gather the contestants, he makes a drone accompany her...called Wix. A strange, and somewhat annoying, drone with wings that can be modified at will.

Along her way, Alma's deviously playful nature becomes clear when she arrives at the stadium with a familiar crystalline Latias and an assortment of other creatures.
Winder approaches the group with a mask on as he addresses them, explaining the tournament before he approaches Alma personally a short time later.

"Alma, why did you bring one of my best friends to this event?!"
"I thought you'd want her to see this grand event. Would you rather her feel excluded?"
"I wanted her to be here for this event, not end up as food!"
"Well she is here now, and you cannot do anything about it. She is one of the contestants and she will compete just like anyone else. If she loses, there is nothing you can do to prevent it. All are balanced here, all are almost equally likely to win or lose...with a little luck, that is."

The Giratina explains the laws of the dimension she set in motion, that none shall stay dead if the worst should happen. Stating that all language barriers are shattered in this place that the contestants will understand each other.

"Don't worry, Winder. I have everything under control."
