The three of them are inside a room within the Hub.
The very first question that Joker asked. 'How many realms do you think there are in existence?'
This question caught both of them off guard. They really don't know what to say for this. After all, just the realms they knew number in hundreds. So, how could they give out a number.
That made them stay silent.
After that silence, Joker led them inside.
He then continued the conversation.
"It was wise of you to not answer. Because, there are way too many realms. I have travelled to many of them and learned loads of things. The formation techniques, inscription patterns, new runes, etc, etc.
However there is just one realm that is very unique. Unique to the point that I have never seen anything like that before and I doubt that I ever will."
As he said he waved his hand and a solar system appeared on a projection in front of them.
