Manalyssia
Mana: it is the life force of the world of Manalyssia. It sustains all life, from rocks and rivers to roses and ravens. A wide array of plants, animals, and humanoid races fill this world, but without mana, all of them would fade away.
Manalyssia consists of two continents: Vespera in the west named for the evening star, and Uzumoku in the east named for the morning star.
