NDParkour is a custom plugin that powers CU's parkour gamemode. It dates all the way back to 2014, as a plugin used by Nuclear District (hence the name, NDParkour). Later, it was updated to work with modern Minecraft versions and rebranded on the user-facing side as CUParkour. Internally, many things are still referenced as NDParkour, and the package name is still net.nucleardistrict in code. It continues to be updated and serves as CU's first custom-made minigame plugin.
