Story
PART I
When he was very young he behaved very joyfully and openly, loved to explore the world and was interested in everything that was possible and not possible. Since childhood he had an interest in collecting all sorts of things, which didn't fade with time. But after a while he found a mysterious hut in the forest that changed his life.
PART II
He looked into this hut in the forest, and miracles were waiting for him there. It's like a human fairy tale. Bags of various powders, a large cauldron with something bubbling green. It was the hut of a novice Voodoo master who had just started his training. Little Fin was interested in dark magic and they became friends, agreeing that Fin would be an assistant.
But something went wrong. The Voodoo master was polite at first, but then he started using the Ending for his own purposes. They forced him to do all the dirty work for him, tease him in all sorts of ways (far from safe), thinking only about their own success in magic.
PART III
And one day Fin ran away. He couldn't take it anymore, every time he came to this place he thought it would be his last day alive. The last straw was to find out that the Voodoo master had lost what distinguished him from a complete monster. He lost his heart. He lost his heart chasing his own goals and ambitions.
And now, after all this time, Finn hates dark magic and voodoo to the point of shaking, and also hates trolls who are obsessed with success. He have nightmares almost every day, haunting him from the past.
