I'm working on an alternative reality story and world based on the Moomin series by Tove Jansson, especially Moomin TV series and the Moomin movie "Muumipeikko ja Pyrstötähti".
”When the comet landed and the cave collapsed, Moomintroll (Muumipeikko )had luck on his side. Not necessarily as good of a thing as luck is generally referred to be, considering when he and his parents, Moominmamma (Muumimamma) and Moominpappa (Muumipappa), were making their way out of the cave he was the only one of the three who got out. Moominmamma stumbled and Moominpappa stopped to help her get up while Moomintroll was running towards the entrance, and on that unfortunate moment of separation the tunnel between them collapsed. The stones blocking the way were too heavy and too big to break, it wouldn't have been as difficult otherwise, but it seemed that their equipment was lost. Only smaller tools were found, and enlarging the opening in the wall would take days. The worst realization in that situation was; there was no food. For sure, before they arrived to the cave they had prepared food and drink for days, even for weeks. It was not in the cave, nor outside. It was gone.
Moomintroll was fierce. He would save his parents no matter what, lifting, kicking and hitting the rocks with everything he got, and the others were helping too. An aftershock happened right when he was reaching for a stone deeper in the opening, and his left arm was crushed when another rock fell on top of it. He screamed and passed out from pain.
He woke up laying on the beach, without having any idea how much time had passed since his arm got stuck near the cave's entrance. He saw a familiar face when he opened his eyes; It was Snork (Niisku), and when they looked at each other Snork burst into tears. Moomintroll looked around and he saw his friend Snufkin (Nuuskamuikkunen) laying there also with bad injuries. Then he noticed his broken arm was supported with awfully familiar items, and Moominpappa's hat was standing on the ground next to him. At first he was relieved by seeing his parents' belongings, but noticing how Snork was avoiding his eyes and now crying even more, he realized something was wrong.
Devastated by the loss of his parents, Moomintroll now wanders the wasteland that used to be Moominvalley with his friend Snufkin, seeking the person that betrayed their group and stole the equipment and food.”
