So, the big thing I am adding to my mod is a quest to help resettle human refugees from Earth. They are found in Human Spacestations and randomly generate quests asking for new homes. I want something really cool to happen when all the humans in an area are resettled. I was thinking of turning off the tile protection in the area when they're all gone, but I want to have something really cool in the area that you can only reach when you can dig it out. Any suggestions?
I was thinking of an OP weapon that is somewhere random and completely surrounded with hard to dig blocks
A mech. From ancient times. Perhaps even fixing it is a quest branch(retrofit to use modern chips and find ancient missing parts etc) . Alternatively a mech-like golem. Fixes like a mech, no riders. Functions like a pet. Not a great choice for enclosed spaces.
