Mermaids

Mermaids are mythical creatures of the sea and the basis for "Mermaid Magic".

Mermaid Government
The Mermaid Government is a group of mermaids that rule mermaids all over the world. The Mermaid Government used to be cruel and unfair. However, they are now different now since they're generous (as shown when they let Caroline keep her tail) and fair.

Mermaid Court
As shown in "Consequences" there's a mermaid court.

Mermen
Mermen are the male side of the mermaids. Mermen are not very common since boys seem to think that mermaids are things for girls. In "Powers and Disasters" it is said that mermen aren't meant to be, hinting that David might be the only merman.
