The Geminis Void is one of a pair of voids that has a cycle of colliding with each other and rebounding. The collision is what causes the universe to renew itself.

Every time a collision happens, many Isolated Spaces are destroyed or damaged in the process if they relied on Geminis for it's energy. Any Spaces that did not rely on Geminis, still remain, but many are abandoned. These abandoned spaces are called Fragments.

In the Geminis Void post, I have a faction called The Template. One of The Templates roles is that of a time keeper, it keeps track of how many times Geminis has reset since it was created. It also acts as a repository of knowledge that most factions can use to skip having to re-discover some technology or arts during the next iteration through Inheritance. Although, if one is strong/smart enough, they can make an inheritance without The Template.

Inheritances have conditions to trigger, and then are either given to the first to meet the conditions, or reveals itself to potential inheritors and then the inheritors must complete the inheritances requirements.
