Overworld map
Short version of the old thread:
"Let's do a succession game in a duplicated raws world!" - There was much interest.
Research was conducted to create a reliably stable duplicated raw set. Worlds were generated. Consensus was for a small world.
The world was created with as high an evil quantity as the world spinner allows before producing unplayable worlds. Also features absurd numbers of megabeasts, megabeast caves, semi-megabeasts, night creature types, evil weathers, evil region interactions, curses, and savagery.
There is no surface soil as it has all been replaced, via the magic of duplicated raws, with unnatural materials like "execrable soot" instead. This has had serious consequences:
There do not appear to be any kinds of tree aside from Willow Trees in all the test embarks I have performed. These only grow near water sources, and are rare. They do not seem to grow back.
There are no surface plants other than grasses in those tests.
Legends mode says every other civilization aside from goblins are officially dead.
Through some still-not-understood mechanism, the game still generates dwarven migrants.
Stone layers appear 'mostly' unaffected, but distributions of divine metals appear to be greatly increased, and DFHack's FixVeins constantly complains about fixing incorrect inclusion types.
[FUN research discoveries redacted, for FUN]
The absence of soil means you MUST farm on mud. No exceptions.
The lack of surface plants (anywhere) means you cannot obtain seeds for surface crops, which means you must grow only underground.
Everyone remember to have !!FUN!!. This world is designed for it.
