(MC POV)
I'm not sure what they were planning for the festival but they've expanded the space to include an open field that was three times the size of my courtyard.
Unfortunately, I have not made this space suitable for non-mortals to enter yet so the people who would be coming here are the gods.
I'm guessing my disciples made use of the connections they made during the battle royale to invite those gods.
Everyone got busy with the setting up of the festival, even me. The only issue was that I was busy tearing things down instead of putting things up because for some reason, my disciples felt that it was a given that there would be decorations of me all over the place.
At first they wanted to put up a giant statue of me in the centre of the field so that everyone could see it no matter where they were within this space and I vehemently rejected it.
If you left the preparations to them, of course they'll make something like this.
