Oceanarium

The Oceanarium is an idea shared between Holly and Grace, introduced at Magna College in the story Anxiety. The girls spend many years designing and planning the project, but the first paradox at Anxiety's climax takes Holly into the sea, and leaves Grace raising a child alone - so the dream of the Oceanarium is never realised. When Grace finally delivers her child, she is murdered by Magruder, who kidnaps the baby. Moments later, Holly, Brian and Joshua (from the end of their time-streams) arrive at the scene, managing to bind Grace's ghost to a Thinworld born from the idea of the Oceanarium. Grace and Holly make amends, and Grace maintains a presence as the Oceanarium's protector.
