This is not an entry per se, because it's late. Wanted to give back to the community, because the game is great. I don't know if there's another way to share these maps besides making an account at mod.io (?) so for now, DM me if you want the map.
Welcome to somewhere that's not Italy, post-human extinction of course. Your beavers have inherited a 256 x 256 area to build on, however, due to the great human die out, their artificial systems that kept the land alive though an aqueduct have rusted away while a primary tributary to a delta has clogged. Your task, should you choose to accept it is to build a beaver empire and restore the land. Use everything at your disposal: build vertically, overcome obstacles, and even rebuild human systems to get the Aqueduct flowing and rejuvenate the land-- just be careful not to flood your own lands in the process.
You'll have abundant wood and land to start, but power for buildings and supply lines will be a constant challenge. Your beavers may also run out of room or die out if you fail to undertake massive projects.
Planning is everything.
