Lireo was first glimpsed in the telefantasya Mulawin, where the Diwatas were introduced as allies of the Mulawin (the titular bird-people of that series). Lireo and its people were explored at length in Encantadia, whose story centered on the royal Diwatas known as Sang'gres. The founding of Lireo and the early history of the Diwatas, as well as much of the backstory of Encantadia, was prominently told in Etheria. Part of the action of Mulawin the movie once again takes place in Lireo.
