User blog:BlueTide/The Tale

Can I ask about this one because it's little bit unnecessary.

I'd seen all around this wikia, including the admins. My question in this blog is about something mysterious(maybe) that most(I think) of you sometimes talking about Undertale.

Sorry because I've too many questions about this one. Undertale starts to interest me this time. I don't know which question I want to ask.. Youtuber The Game Theorists starts to make a theory about this.

Ok, can someone tell me about Undertale? All of it(if you can). The lore about this one.
