Actually, you know what? I bet you Sonic ‘06 takes place on June 21, exactly. The main Soleannan religion worships the sun as their god, Solaris. What better day to hold the Solaris-honoring Festival of the Sun than on the longest day in the year, when the sun will be out longer to celebrate?
Sonic ‘06 takes place over the course of two days (according to Tails’ line in Crisis City, regarding Elise’s death: “The date of this incident was two days after the Festival of the Sun”). Which would make the day that Elise “died” - and the day that Sonic actually died… his birthday. June 23.
Sonic was probably visiting Soleanna at the time to celebrate with his friends. And instead, he was murdered and the world ended.

I'll be upfront with my opinion, which mirrors my opinion in regards to my field: using AI will only hasten your own obsolescence. The point of fanfiction is not to crank out fics, but rather to enjoy the hobby and communities of writing and fandom.
