Shadow: OK OK JEEZ I'LL DO IT
(*This got convoluted too fast so here is the story of DeceptionTale Shadow's story is next chapter*)
(*Also, (* is Shadow irl talking*)
So basically, DeceptionTale (my original universe) was a universe somewhere between Undertale and Underfell , (which is why there is no UT Shadow or UF Shadow) in which basically everyone acted like their Undertale counterparts unless they wanted something from someone or were afraid (or you were a human) (also instead of monsters there were white-souled humans who could use magic).
The first fallen human was called Sam, rather than Chara, then the story goes the same way as the Undertale story, until Asriel dies. The King goes insane, exiles the Queen into the Ruins and decrees that all in the Underground would bow to his rule (like dictatorship kind of obedience) with all rebels being executed without mercy. The people REALLY didn't like that, so they killed him, and the Underground fell into a mildly-peaceful, slightly unstable anarchy, because no one knew where the Queen had gone (she was escorted at night and the guards that escorted her were slain by Asgore's own hand) and was kept from total anarchy and war by Undyne, who 'dealt' with troublemakers.
A human fell, and was killed by a Dog Guard in Snowdin. Their soul was a vivid
blue, and it was taken to the castle and held in a container, which was located next to a container holding the stuck-together souls of Asriel and Chara (which had lasted because of Asriel's Boss soul and Chara's human one).
Shadow's story begins 4 dead humans later.
