Nelly the spa owner is a woman who can be found at the Anachronia base camp.
Her mother was constantly busy helping people and was killed when she walked into a nest of basilisks. Nelly decided she wanted a life of relaxation instead. When visiting Varrock Museum one day, she tried touching a special cape that temporarily turned her into a squirrel. This made her sick, so she rushed into what she thought was the ladies' room, but was in actuality Mr. Mordaut's office, and threw up over his desk, ruining several papers about the Second Age. Mr. Mordaut found the incident amusing, despite Nelly's expectations, as the papers were cursed. He'd been trying to break the curse when Nelly had done so accidentally, and she got a medal for doing so.
