At the top of the mountain, I learned a few things.
First, I learned that it’s possible to have a pool of bubbling lava in an otherwise-normal looking field. This is good information to have because it means this area’s seismically active. (It also means I won’t be swimming over there any time soon.) All the more reason to build solid stone walls for my cave walls wherever possible.
Second, I learned that there are no towns or cities or other signs of life anywhere in my immediately-viewable area unless they’re also underground. I certainly wouldn’t blame anyone for going underground here, but it means to find other people I have to either hope this is just an abandoned area, or hope that I’ll dig into the sides of their houses.
I’m sure they’ll be totally understanding when I do that.
Third, I learned there’s a much bigger mountain to the east of my current position — but it’s far enough away that I can’t see it unless I’m on the current mountain. So digging to the next one the same way that I dug to this one is probably my safest best. Because digging holes to reach bigger piles of dirt is a thing here.
Finally, I learned there are sheep on the other side of the mountain. Do I go capture some? I haven’t decided yet. Sheep would be a good thing to have though. I could make clothes somehow, and mutton. That would be good.
Anyway, that was today’s adventure set.
