I really want to insert Laputa into the novel I'm writing but I feel I should call it something else. It's not an important part of the book, I just want to feature a destroyed sky island for the characters to come across. It's an out right ode less to Gulliver's Travels and more to Castle in the Sky--which outright calls its sky island Laputa. Should I just call the rock Laputa or is that in poor taste?
