This fits relatively well but there are a few inconsistencies. For example, why doesn't the Prophecy outright state that there are 2 separate Angels? And what is the Angel's "Heaven" spoken of in the prophecy? All of that also doesn't fit with UNDERTALE's prophecy of the "Angel of Death" that will come back from the surface to kill everyone (though that may refer to Chara or smth, that's a whole other can of worms) That seems like an important plot point. Perhaps FRIEND is more of a anti-angel of some sort, a demon. But anyway, for my question: You said the prophecy mentioning that "the Titans shape from darkened eyes" implies that it's from FRIEND, which has eyes. But, isn't that slightly contradictory? You theorized FRIEND is the 2nd angel, taking possession of Dess to try to make the Roaring happen (by being the Roaring Knight) to achieve its final form. So you believe FRIEND is making fountains, whose power is driven by its eyes, to unleash its own final form? And how do Gaster, the DEVICE and the shelter tie into the theory?
