Resi

Resi or The Shapeless is one of the Fragments of the Core in Timeline 1272B. He is a kitsune with two tails, a crimson hoodie, and the ability to shapeshift. He spends most of his time in his home in [REDACTED], [DATA EXPUNGED], but frequently goes to other timelines to visit Comrade Shooty, Aaron Greysoul, and other friends.

Origin
The Shapeless was one of three Fragments of the Core, along with The Wanderer and The Architect which were separated by the Big Bang. The Shapeless wandered around the young universe for the first 13 billion years, before being given form approximately 0.8 billion years ago. It is currently unknown what The Shapeless' original form was, but the most probable theory was that it was Resi.

Discovery of Alternate Timelines
In 1422 AD, Resi was the first in 1272B to ponder the idea that his universe was not the only one. He abused his shapeshifting powers to attempt to shapeshift into a portal to another universe, and to his surprise, it worked. He spent the next 12 years studying and exploring the idea of alternate timelines. In this period he discovered there were different layers of alternate timelines, which he neatly labeled with letters of the alphabet. He also discovered the Zero Point, a consistent timeline across layers. He combined these two ideas together in 1434 AD to create RSFTL, a labeling system for timelines, which is now widely used across the B-layer.
