I want to make a roleplay where the canon New Republic is working on a top secret science project analogous to the First Order creating Starkiller Base. It can’t be something already depicted in Legends or Canon; so I don’t want it to be teleportation, mind uploading, time travel, matter replicators, anything to do with the Force (unless it isn’t blasphemous) or any other super-common sci-fi trope.
Does anybody have any good ideas?
