Tellirian is a fantasy world inhabited by all kinds of legendary creatures, beings and entities. It's basically an alternate Earth where magic is always the rule and never an exception and it's split into seven nations:

Nation of Alphydel: A medieval nation based on Europe in the Middle Age and the Germanic Folklore. It's inhabited by elves, dwarfs, fairies, monsters and legendary beasts

Nation of Eksilion: The most advanced technologically nation. It's a mix of Horror Fiction and Science Fiction and it's inhabited by ghosts and undead beings

Nation of Imagiya: The nation of witchcraft and wizardry based on the Victorian Era. It's inhabited by human mages as they must study magic since their childhood

Nation of Omicronos: Based on the Chinese Folklore and Kung-Fu. It's inhabited by anthropomorphic beings (which are very different from the people of a certain planet)

Nation of Uta: Based on the Edo Period Japan and the Japanese Folklore. It's mainly inhabited by yokai, but rarely, humans also reside there

Nation of Teriuv: The Heaven of Tellirian. It's inhabited by angels

Nation of Nis: The Netherworld of Tellirian. It's inhabited by demons and evil creatures
