Terra Palus by Lukah, updated for Factorio 2.1: a hybrid swamp moon of Gleba with both biters and pentapods. Mine Palusium ore and use UV light to freeze those that would see you destroyed.
Your base stays, the fork keeps all prototype and setting names, only the mod name changed. Remove original Terra Palus and add this one before loading. Lamps and spotlights are picked up again on load. One difference: unexplored chunks of Gleba will generate vanilla plants and mud, since the original changed them.
