It's been a while since we have added new quest locations into the game, but it does not mean we have nothing coming a lot. In fact - we have, it just took us longer than expected.
Here is some info on what will be released eventually.
We are working on a new set of random locations similar to dungeons and mines. They are Ruins:
Unlike mines and dungeons, ruins are a bit larger and more complex - there are sun-locations in them, they are not in all in one space.
There will be 12 of them.
What do you think about it?
