My version of the SeaWitch from the Little Mermaid.
Her species were created before that of the Mermaids as an experamental race. They are very unstable magically and must devour magical creatures to sustain their own life force.
Meaning they're main food source is the later creation and they're cousin species Mermaids.
In the turn table Znidaria has just made the deal with the mermaid, and is giving her the potion, which happens to be the end of one of the SeaWitches tentacles. Within the tentacle vile is stolen life force. Magic taken from others to live is what will be used to grant the Mermaids wish ...and ultimately take her life force away in turn
