Thessa and Nerida are sisters of the Mediterranean sea. They can draw their heritage to either dangerous sirens or helpful sea nymphs, depending on which relative you ask.

Will these differences mean the grow apart or will their mutual love for the ocean, always bring them back together? #mermaids #sirens #seanymphs #sisters #islandliving #SparkdCreature #SparkdChallenges
