This is long overdue. In order to one day actually understand this subverse, we must continue with our treatises. We have established what constitutes "bestiness", and not long thereafter we were able to discover the true meaning of "everiness". Now our task is to explore "subbiness". What is a subverse anyway?
As the name suggests, subverses are mini-universes that exist within this plane of exist, within this timeline. They pop in and out of existence from time to time; sometimes they are accessible, sometimes they are not. Sometimes subverses contain plentiful amounts of activity and life; sometimes they are as dead as stone.
Because this subverse is the Best Subverse in History Ever, all other subverses are judged by its standard. If the degree to which a subverse can be accessed mimics that of this subverse, then it is accessible. If a subverse is not as accessible as this subverse, then it is not accessible. This metric also applies to energy and activity.
So don't you see! This is why it is so important to keep this subverse alive -- for if it dies, so too do all other subverses die!
Hopefully this has given the reader some comprehension of what a subverse is and, I hope, an understanding of why the Best Subverse in History Ever simply must survive.
