I think I do.... Might be wrong tho but so I think its time slipping.
Their race during their young years time slips into the same period as a main body. This can be alternate realities as well. They then continue from that time as they eventually stabilize being 4 or so people at once. They said earlier it's common for 3 or 5 but some have even 10 or more but those are more unstable. It's alternate versions of them tend to fall into one time and it's just something that happens to those race ig?
And I still don't get how asangard race work. Wtf are they. They are one person but have different identity? Explain to me through metaphor or something
