Entry 703 Something has changed in the multiverse, the balance between positivity and negativity has almost been restored. Yet, how could this happen in just one night? It must have something to do with Dream, he has been acting different lately, he acts as if he knows what's going to happen and soon he will have us under him, he's much more calm but it's an icy cold one not warm and comforting. That's not even getting into how different he looks physically! He seems taller, his posture so perfect and he carries a tricking SWORD with him everywhere! He even has ghostly golden WINGS you heard me WINGS. But the biggest thing, is his feelings concerning nightmare, the dream I know wants to SAVE him and get his brother back. But now... he wants to FIGHT and kill nightmare. And damn does he want him DEAD! There's no way that this all happened in one night without something serious occurring. No. Somethings definitely wrong here. Classic and I are going with the usual squad to nightmares castle, this time however. Dream insisted he come as he says "I know a way in." But classic and I have a greater reason to attend... find out what happened to dream... And how to SAVE him. Entry end But what happens when ink and classic uncover something much greater than they could imagine, and are they the only ones? Book 1- possession (you are here) Book 2- reunited
