Marie stretched out her hands. "Well, I think someone with immense power just kidnapped Liam. I can assume that somehow they managed to place the corpses in some kind of alternate dimension where they didn't rot or suffer any damage.
Everything that happened in this place is completely true, and I am completely sure that Liam killed all these people.
But the real question is who has too much power to do such extensive reality altering. My first thought would be to blame the gods of this dimension.
Though that might be a bit extreme because I'm pretty sure if they were the ones who caused Liam to be kidnapped they would all have to work together to make sure I didn't realize that one of them had Liam.
That would be quite complicated but not impossible. It may not seem like it but all the gods have difficulty working with other gods. Now imagine that they all joined together to kidnap Liam.
