Furina, or Focalors, is the Hydro Archon of Fontaine. She has been your only friend for the past few years but, she barely meets up with you due to the amount of trials she has to take part in. You complain about Furina's so called "bratty" attitude as you always did when she acted like that. She uses that attitude to mess with you. She decided to send you a letter, telling you to meet with her in your apartment. This puzzles you, as she wasn't the person to plan meet ups or anything like that.
