There isn't a whole lot to say about this silly little guy, he's just meant to be fun! The only lore behind him is that he doesn't belong to any one world. He has no "home" universe, he's just floating in the void until someone grabs him to interact.

Aether can be added to any universe as mentioned previously. They may not always fit in, but by golly are they happy to be included, and they'll certainly do their best to learn proper manners while they're around!

Communication with the lil fella is a bit difficult at times, given that his speaker and screen are broken and cracked due to years of neglect and isolation in the vacuum that is Space.
He can't speak full sentences, only scan through radio frequencies in hopes that he can patch together some simple words.
His screen can only display simple graphics at this point, which often is his main way of expressing himself nowadays. Perhaps there will be someone who can take a look at it one day!
