Are these skin sets in the same universe or all separate?

I have a feeling that the Deep Space is in the same universe as Eternumn, but it doesn't feel right to see it that way for some reason... So, maybe it's related to the Dreadnova sets?

Then that leaves me to wonder if Star Guardian takes place in the same universe as Dark Star or anything mentioned above? And where does Super Galaxy fit in this? I guess I really just want more lore for the Eternumn skin line... Idk.

Also, does anyone know if Academy has a connection to the Star Guardian sets? Or is it it's own thing entirely? [zombie-brand-clap]
