After Katarina emerged from the Green Gate ten years ago and became one of the Five Rulers, she changed significantly from the person Tobias had once known.
Katarina first dedicated her life to creating the BloodRaven guild and she expanded its influence across the whole of America and made it into one of the most powerful guilds in the world before finally hiding away in this mansion and refusing to leave anymore.
The only interaction Katarina had with the outside world was through her Gift, which she used to support all the members of the guild, and through the vice-captains who sometimes came to give her reports of what was happening. She never left this building and had no means of communication with the outside world.
