Merlot is a Lugia, the lady and caretaker of Castle Draclugia. Like most legendary Pokemon, rumors abound about her: from her age, weight, and dietary habits to other more scandalous secrets involving her servants and backroom deals with the local guild leaders, Merlot is a riddle wrapped in an enigma inside a fashionable velvet cape. While all rumors about her being a vampire have been confirmed as false, it is true that she loves Dragon-type Pokemon and dressing her servants up as maids, for whatever reason. Beyond that, no one knows much about her early life, as she's known to be at least a couple of centuries old and there are no known reliable sources for that timeframe (outside of perhaps Merlot's library, or Merlot herself).

Merlot in her younger days displayed a strong sense of opinion, even in naivety. Despite this, she did not have many friends, let alone acquaintances, and kept to herself in her room. Merlot has lived in Castle Draclugia for her entire life and usually keeps to herself and stays out of outside affairs, sending her servants to do errands for her when necessary. Throughout her life, she's collected an assortment of helpers who usually end up staying with her for the rest of their lives.
