Okay, So I have questions that need to be answered and in a codified fashion.
1.) At which point did Earth-Rho deviate from Earth-Aleph? I believe this was discussed previously. If I remember correctly this was with the arrival of Scion.
2.) We know that Earth-Bet was heavily laced with Shards by the warrior entity. We've been using Earth-Bet numbers to estimate the number of capes and/or potential capes for Earth-Rho. Trouble is, we never confirmed if these numbers hold true for Earth-Rho. Earth-Bet was supposed to be the Warrior entity's ideal fertile ground. That was the dimension/reality he chose to heavily seed.
3.) In this regard, are we looking to say that Earth-Rho was Earth-Bet adjacent at the time, or was it a split-off directly from the arrival point? If so did that duplicate shards, or did both points in the multi-verse get an equal measure? Or was it unequal?
4.) Earth-Aleph sustained losses of only half a billion, which was getting off light. Earth-Bet suffered much damage, though it could have been worse. Earth-Gimel also so a decent amount of heavy conflict, especially around New Brockton Bay. Earth-Bet saw the United Kingdom cratered. Other realms varied in damage by significant amounts. We've discussed that Earth-B saw a great number of casualties. We determined that there were roughly 1 billion survivors, but that was using Earth-B numbers. Are we still holding to that for Earth-Rho?
5.) Golden Morning was 8 years ago. With the end results in New York-B at the hands of Khepri, it seems there is evidence of severely deviated or damaged shards. Do we have an idea how we're plotting out those?
6.) Also, if Earth-Rho is very similar to Earth-Bet, is there any thought to this world's version of the Triumvirate, and other highly known capes?
7.) Also, was Ash City called Ash City originally, or did it get renamed in the aftermath of Golden Morning?
1.) Yes, we did establish this, it was around the time Scion showed up, though I'm fairly sure we also decided that there were already significant differences in Earth Rho. my own personally planned differences include: a smaller population of people; more people who evacuated during Golden Morning, expecting worse from Scion; generally less shards initially, and probably some others.
2.) Y...yes we did. We had a whole long conversation regarding the ratio of capes to civilians in Earth Rho (the cape to civvy ratio is MUCH higher). Now the reasoning for this varies, but the stuff that we have decided for sure as part of the contributing factors are as follow:
>Lots of people ended up evacuating to Earth-Rho, as well as returning there, once Golden Morning was over. Keep in mind it's non-canon so we can basically do what we want.>Scion DID hit Earth-Rho pretty bad, but he didn't destroy as much fundamental stuff, though he did demolish a lot of infastructure. Him hitting it hard means more people have a likelihood of triggering. Many initial triggers here were buds from other shards.>This one is a possibility, not a certainty, but what if when Golden Morning ended, the path to X dimension where the rest of Scion was, opened into Earth Rho, showering it with his shards.>I don't know if Worm ever defined it, but we know that the Thinker Entity landed in a certain POPULATED world. I don't think it said which one. What if it was Earth Rho, or what if we CHANGE it so that it is Earth Rho--whatever remains that is.>The initial struggle to survive and rebuild was very dangerous and unfamiliar for the majority of those who returned to Earth Rho. As a result there were a lot of triggers that happened during that 8 year period following Golden Morning. Now with a higher cape mass, people trigger more often due to their fights and the unique problems relying on capes in society bring about.>Miscellaneous.Oh, as a final note the ratio for human to Parahumans is "2,500:1".
3.) Already sort of covered a possibility of why there are more shards there in #2. Any other possibilities are probably going to be linked to a mysterious
Third Entity.
4.) Yes we're holding to that, because Earth Rho is populated by people from more than one alternate Earth who have all come to Earth Rho. Many people didn't go to Earth Rho since there were, what seemed to be, better places to go, or more familiar places.
5.) Not sure what you mean by plotting these out. Do you mean, "where are they coming from?" because I addressed that in #3 and another potential reason in #2. In fact, the ONLY likely reason that there are so many damaged/deviated shards is BECAUSE of Golden Morning's conclusion.
6.) Based on canon, even if there were other people who had the same names and personalities as Alexandria, Eidolon, and Legend, there remains the problem of...well, the Entities only chose SOME Earths to seed, whereas they just straight up didn't for others, or gave only a few shards to some (or prepared some worlds in case they needed them or wanted to harvest them as well). So, seeing as we didn't see Khepri control any duplicates in Golden Morning, and also to avoid confusion, they functionally don't exist in Earth Rho. What we COULD be asking ourselves is "What was the cape situation in Earth Rho BEFORE Golden Morning?" Also, I'm going to assume that either the Simurgh WAS moved to a facility in Earth Rho, or that she was not, we should decide on that. Not sure what we want in that regard.
7.) Ash City is effectively a totally new city. Meaning it was built largely from the ground up. So yes, while it may have had a few other provisional names it has functionally always been called some variation of "Ash City."
Hope this helps.
