Spectra's home and school, Spagonia and Spagonia University. Specifically, the city of Columbia is the exact location.

This was during Spectra's graduation after Mobius being healed back together, Chip having his memories back and both Eggman and Dark Gaia defeated once again. Congrats, class of 2016! Spectra, you are the best! Very proud of you and may you have a great future. Thanks for the invite and you being a good friend. Love you!
