[Meta thread] Iron's PokeRole Adventure: The Skull Ruins

[Iron]

Here's how I built this scene:

I made a list of Encounters that might be found underground (Pokemon and Items, mostly).
This led to the creation of the Biomes. Which led to more lists of possible Pokemon - ice, root, coal - that weren't on the original underground list.
I also have a list of some plot-related/Library-related things.
Looking at all these lists, and thinking about New Zealand (Creshire's inspiration), I came up with the cavern as representative of many of them.
