Queen Lilia assumed the throne after her unknown parent, the previous monarch of Deltora and Queen Elspeth's child, passed away. Lilia was among the numerous rulers of Deltora that Crian had sent messages to, telling the royal family of the poor conditions in Del. All of the messages were ignored with a promise that Crian's concerns would be attended to when "time allows". All of the monarchs had signed and stamped the response written by their chief advisor, and Lilia was no different.
After Lilia's death, her son, Alton, succeeded her. Jarred later recognised her name among Crian's collection of letters from the previous kings and queens of Deltora.
Nothing is known of Lilia's physical appearance, though she briefly wore the Belt of Deltora when she assumed the throne.
Lilia, like her predecessors, was manipulated by her chief advisor. She was kept oblivious to the suffering of Deltora's people and signed and stamped whatever documents her chief advisor brought her.
Lilia, as the ruling queen of Deltora, had access to all of the land's resources and guards. As Adin's heir, she had the ability to make full use of the Belt of Deltora and its powers, though she never did so.
