Dungeon geomorphs and megadungeons--what's not to love?
I've only recently come across Carjacked Seraphim, but he has made some interesting posts. I'll probably have to stop over at his place in the coming months to see how things shake out. Of course, it was this little number on geomorphs that first caught my eye.
Then I came across this post about supercaves. Thank you, Seraphim for making this known to me, because there is much goodness therein. And it is further proof that NPR can be a force for good in the world.
