Nexus

"Go, my Son! Find a reality where the Hive are extinct and our race alive!"

- The Father's dying words to the Son

The Nexus is an interdimensional realm created by the Father with the reminder of his life-force and ultimately sacrificed himself to create it. Being an interdimensional realm, it connects every timeline and universe in time and space that exist, including alternate timelines and universes.

Lore
Centuries before the rise of humanity and rise of the dinosaurs, a great war took place on Earth, known as æther at the time, between the Hive and an extinct race of supernatural beings. With the Hive and their Empire, the extinct race were beaten and pushed to extinction, however two survivors; one known as the Father had used the last of his life-force to create the Nexus, which would connect all timelines and universes in time and space. His dying wish to his Son was to find a timeline where the Hive would fall; leaving him to endless search hundreds of timelines and universes in order to find this downfall of the Hive.

As time went on, the Son began to transfer his soul and life-force to other bodies whenever one would die off. However as his hosts died and his memories, soul and life-force transferred to the next, he became losing sight of his mission given by his Father; eventually forgetting that he was the last of his race and about the Hive.

He later took on the name Mr. Tachibana, naming himself after his previous host, and eventually running the Armoury and using a refreshment to clone himself in order to use the Nexus, which he had forgot the true purpose of, in search of weapons, locations, and "friends" to bring back to his Armoury.
