How Majestic This Wondrous Earth

How Majestic This Wondrous Earth is a fan-made expansion hack for His Majesty The Worm, created during the September worm jam, with the aim of creating depth to overland travel and exploration. Its main features, aiming to complement the existing dungeon crawling, are a method to randomly generate overworld realms with varied terrain; four new environmental hazards to replace or complement darkness (heat, cold, miasma, and storms); and a random weather system to help deliver those hazards and other interesting events alongside HMTW's existing Meatgrinder system. It also adds additional small rules suited for use in an overworld adventure: currently, outposts, traveling light, and pack animals.

Right now it's in a pretty barebones state, but I plan to update this hack in the future with added art and better formatting (prettier tables, for one thing), and may add additional supplementary mechanics, like more weather or hazards.
