Maybe the River Person is Gaster, or knows Gaster? Maybe they aren't Gaster though, because it'd be kinda weird to warn someone about yourself, and because Gaster can be found in other places. Plus Gaster fell into the CORE and was spread across space and time.

That makes me wonder...CORE is all caps. Could it stand for something? LV and EXP did, and they were in all caps too.
