You have an account on norrebro.space, which is a #Mastodon server. I have an account on techhub.social, which is a Mastodon server. By me sending this reply, my server is speaking to your server through #ActivityPub.
The fact that my account is hosted by a Mastodon server makes no difference in your ability to follow or interact with my posts, so long as both our servers understand ActivityPub.
There are other servers that also speak #ActivityPub. Someone with an account on calckey.social, which is a Calckey server, can also reply to this post because Calckey speaks ActivityPub. That you are on Mastodon and they are on Calckey is not important, because the servers speak the same language.
To use your example of realms, I think that rather than saying Mastodon realm or Calckey realm or whatever, it may be helpful to think more along the lines of each server being a realm. norrebro.space is the realm you live in. techhub.social is the realm I live in. They talk.
