[@Memory] For anyone interested, The Tesseract, though this may come as a spoiler, is visible to anyone from Myriad Reality. This will be revealed later, but due to all the characters ability to travel between reality, everyone essentially have taped into a similar multi-dimensional energy that it is made out of. That said, [@Etcetera] Misty can also see it, even if Soldier Boy didn't present it to you.
