After Sans and Papyrus escaped Gaster and his never ending tests, leaving him alone in the void, Gaster created a realm of his own, similar to the ruins in the underground. There, he used his last bit of USABLE Determination to create one last test subject, whom he named W3A43R. Upon creation, W3A43R had developed a talent for weaving threads of cobwebs to make "streamers" that she used to decorate her captivity cell. Gaster took note of this and gave W3A43R the dangerous task of weaving strands of CORRUPTED Determination together, just as she had done with the cobwebs. She did so successfully, and thus created a string-like substance called DNA (Determination Nodules and Aptitudes). Gaster then assigned the strand of DNA to a rat, which affected it's ability to complete puzzles and it's overall personality. Since he had a surplus of CORRUPTED Determination threads, he renamed W3A43R and gave her the name Weaver and the task to weave DNA. Though she never knew what Gaster did to her self-proclaimed "works of art", she dared not to question his ways. That was... Until the three of them showed up. Get ready, Undertale lovas because I've put soooooooo much thought into this AU and I'm really happy with how it's turning out. This will most likely not be as long a story as Isolation but it will be a priority for a while! ~Bread
