Bibble juniors plan was to wait a few thousand years before he returned to earth. To make sure nobody would remember the Bibble race and so he could try and befriend them, just to bring them down to hell with him. The gods gave him eternal life as a sort of empathic gift. But it only made his hate towards humans stronger
Seeing them developing magic and houses made him feel left out of what he could have had, but was sadly stripped away from him without his consent.
After a few thousand of years. Bibble junior was ready.
His first appreance was in the land of faries. He befriended a young girl who looked the most like a human, because she didn't have wings. He wanted to target the weakest of them all but sadly this plan failed. Because after achieving an amazing deed she got Wings which made his plan fade away.
Instead of giving up, he decided he still could kill all species. He just had to figure out how.
He thought about poising their food source but figured out quickly that, that wouldn't work due to more food always coming back.
His only way to kill the faires, was too kill their leader, claiming leadership over all faires and showing them the true power of the Bibble.
So one night. He snuck out of his hiding spot, he was holding a sharp knife in his hands and got into the Queens room without anyone realising he was there, but before he could kill her and claim leadership, starting his plan for vengeance. He saw a bright light from the window..
It was his father
