“Hello there, I am Dr. Gaster, the Former Royal Scientist who created the CORE, the DT Extractor, and my own two sons, Sans and Papyrus, all using my vast scientific and magical knowledge.” Gaster told you.

“I had accidentally fallen into the Core one day, you see, and got shattered across space and time. I was trapped in the Void, but I was saved by Frisk, a very determined young child.” Gaster explained softly, though the memories were painful.
