Hytale has officially released that there is 3 Zones you can start the game on: Emerald Grove, Howling Sands, and Borea.
But a big question is: how do you reach Zones beyond the starting ones?
It seems that you'd have to defeat a boss to open a portal to the next Zone, but by looking at the Orbis art, it seems to be that all of the Zones are connected and can be accessed by simply walking.
I was thinking about this for a while and decided it would be a good idea to make a discussion about it.
