Apparently there is a way to return to Euclid, it only takes about 256 galaxies though!
Check the video here, I think it deserves a watch:
Until now, we thought that after the last known unique galaxy Odyalutai, names were just being randomised, with the next galaxy just being a copy of the previous. This was according to info from Reddit user sHuRuLuNi, who had been posting documentation of his travels across galaxies.
However, as you can see in the video above, the next galaxy turned out to be an interesting surprise! This makes me wonder if there has been a change since, maybe a bug fix by HG, or if the previous attempts were flawed due to use of a glitch or possibly involvement of mods.
Very interesting and actually does not quite surprise me to end up back where it all starts!
