Thank everyone for the answers!
Thanks for reminding me, Nefrarya, but I'm prepared for the time when the final game releases. Which means, I don't really care about the actual character's fate, I'm just deleting it and will create a new world. :) I quite love the game.
I think you are right, Altimely: probably the wast majority is waiting for the Mistlands update to be released and configure their own mods to that.
If I'm not mistaken, 2 other biomes will be populated in the future, right?

Also, Nobber and Complaintdesk: Thanks for your suggestions!! Appreciate that!! :)
