MERMAIDS

Previously you were not allowed to marry a mermaid unless Medical had been cleared.  This rule has been changed to allow it but discourages it: 

You may marry in a mermaid, however prior to Medical restrictions being cleared they could die quickly.

• If they aren't able to swim in the ocean or in a swimming pool, and they don't die, then they will revert in a few days to fully human.
