Leuko thought they knew everything in their life, that was until she found out about their biological dad. An elf who went away before they were born to go fight in battle against many other species who aren't as nice as they may seem. Leuko was told that their dad left them for another family but when they realize that isn't true, they second guess themselves and ask why their mom and their brother, who she didn't know was her biological brother until now, had lied to them. As Leuko fights their way to learn more about who they are and why they were brought to the Realm of The Unknown, they learn about many types of species, why the Elven species is one of the only neutral species in the Realm, and why there are so many species that aren't as nice as they seem. As Leuko uncovers the secrets lying behind each forsaken door, they realize what's really behind why they were kept a secret from the land where they were born and why it was safer to keep them "behind bars". As Leuko gets wrapped up in battle alongside every ally, against every foe, they uncover the ultimate secret that's been inside them all along.
