The outside world and Amazons

[AmiMizuno]

I’m curious what if the Amazons have a common spot ? Like the main island is hidden but they use smaller islands if they had to. For example, helping shipwrecks. Or in some cases need to heal Steve or others

Remember paradise island is not just a piece of land in the ocean, it's a part of Skyworld just like Olympus is. The only way to cross the "border" is with a portal (boom tube or anything like that) or a divine intervention (like when Steve got to Themiscyra). Thus there is no point to have several islands.

It was a regular island until the gods or Amazons decided to leave. They are in a pocket dimension they can control.
