Personal theory on the prophecy and what it means.

Alright time for my huge Deltarune theory. I believe the prophecy isn't set in stone, and the part we haven't seen is what is displayed in the ERAM game. Snowgrave will be the route that falls into the prophecy, and pacifist will diverge. However I think within that, there's a fair chance the "canon" ending is going to be snow grave which leads into Undertale. My supporting reason for this is that I believe the weapon gerson gives us isn't the hammer. The weapon he gives us is hope, that weapon is what will power us into the correct path, but as for snowgrave the hope means nothing. The hope only provides solice for susie and ralsei. Hence why tbe prophecy, which i said I think is for the snowgrave route, describes it as a terrible weapon. That hope will be Susie and ralseis downfall as they dint realize wr aren't working with them but against them.
