Rikki Grey

Rikki is a daughter of Hades who was trapped in the Lotus Hotel and Casino in 1925, not long after she turned 23. She only got out because she recognized Alecto when she came and took Bianca and Nico away from the hotel. She followed them and was overwhelmed by the changed world at first, so she didn’t make it back to camp until a few months after Bianca’s death.
