Biob

Biob is a verse found inside of Unob, and has 2 Tronobs (other than the borders) located inside of it. They are characterized by their relative nonborder stability, ejecting only 1 tronob per hour, which is why they are home to Hapras. If more or less than two tronobs exist within a Biob, it explodes with a force of 10^748 joules, leaving the Tronobs inside orphan. Hapras regularly harvest this energy. Also, orphan Tronobs have a lifespan cut to 1/10 of normal.

If the Tronob arrives at another Biob, then it has an invalid 3 tronobs and explodes too, setting off a chain reaction that can leave an entire Unob sterile within 19 Earth years. And then... the Unob is invalid too in that it has no biobs, so it explodes. However, the entities here are blast resistant and constantly migrate between Biobs. If there are no biobs, they can migrate to other Unobs, but that will take a while.

Borders
The edges of a Biob are more unstable. They eject 686 tronobs per millisecond, earning unstability 30%, but this is still less severe than Null System. No entities have every ventured here.
