The waters of Mermaid Fountain are surprisingly deep. A lip with only a couple feet of water catches coins thrown in for wishes. But the center of the fountain around the statue drops down into inky darkness. Small brass placards warn parents not to let their children go wading.
An actual Mermaid named Avery lives in the depths of the pool, which connects to a sunken grotto. The grotto is magical and links to the Fairylands, as well as to the river near Rainbow Rocks. Lilith once lived with the mermaids there, but is estranged for reasons she's not willing to discuss.
