Blitts are little, rocky chunks of living rock. The lead variety can be found in the Paper Mines, scrunching around, the other two varieties being iron Blitts and coal Blitts. All three can be found in the Kingdom of Heat, a general wasteland that was overcome with volcanoes and lava rain. Despite this, it's more lively than you think, as Smoklent and Roglama actually live there freely, perfectly fine with the weather and it being kept there by the Fire Shield. It's not like they mind. With the correct gear, people can venture there and see what it's like, but honestly, it's a bit of a dumb thing to do because, well. Everything's on fire.
