According to Lewis scholar Paul F. Ford, Lewis created the character of Ramandu's daughter having been inspired by J. R. R. Tolkien's Middle Earth elves, specifically Lúthien and Arwen. Ramandu's daughter has also been compared to the angelic entities known as Maiar, also featured in Tolkien's novels. Douglas Gresham, Lewis' step-son, created the name Lilliandil for the 2010 film version of "The Voyage of the Dawn Treader". Ramandu's daughter was the subject of literary analysis by various scholars, with her goodness and her marriage with Caspian X receiving attention. The character has been associated with various Christian virtues and women in the Bible.
