It's hard to say for certain. Sometimes stories like 'La Esclava Blanca' combine real-life elements with fictional creations to make an engaging narrative. You'd have to do some research to know for sure.
Since I don't know the exact story, it could potentially be about a figure who met a watery end and was considered beautiful in a way that defies normal expectations. It could be a story about love and loss, where the person who drowned was remembered in a special way that made them seem the most beautiful. It might also be a story with a moral or lesson, perhaps about the transience of life and the power of memory.
One possible theme could be the concept of beauty in death. The idea of the 'ahogado' (the drowned one) being the most beautiful might imply that there is a certain allure or significance to the state of death.
