Xynar's reality

A creation of a human and a Jinn, Xynar is a never-seen-before book of sorcery. When someone opens Xynar, it sucks them inside of it, and throws them into an alternate world of magic, where they need to fend for themselves and survive. Throughout their journey Xynar will remain present with them; it has blank pages, and it narrates the experience of its victim. When its pages become full, it means that the person has survived for long enough, and officially conquered the challenge of Xynar, and is worthy of returning to the real world. Xynar's third victim, Alan, has been put on the 7 island chain, Gwaxyguen, of the AZ Planet. Alan will later find out that he needs to learn the types of magic that are specific to each native citizen of each of the islands, to be able to unlock the strongest magic of all, existential magic, and face the 2 gods of the planet to try and fix what their cynical acts have ruined. Alan will either win the fight, which would end Xynar's pages and teleport him back to the real world, die fighting the gods, or have his journey abruptly cut off on one of the islands.
