Its Realtime purpose is an IDE (codesmith developer access), its Runtime (U/I) function is as a space building simulator, operating in conjunction with the SuperWikia 'Navigator' user interface to simulate space economics and fleet operations. It allows users (known as 'data fleet navigators' or DFN's) to compete in tourneys over vast regions known as 'expanses' and to create envoys that manage onsite and offsite stations. Using additional SuperWikia components, users may enhance their experience with plugins and 'dataplates' that help build the Runtime environment. Codesmiths (SuperWikia Alpha developers) can also build on top of the codebase using 'transcribes', acronym/algebraic encodes that differentiate codesmith works.
