Laguna

Half Merfolk/Half Human
Being two of Amaranth's most populous species, and ones most dedicated to farming (in, and on the shore of, the rivers that run throughout the city), it was only natural that quite a population of hybrids would pop up. Now almost as numerous as Half-elves; Laguna inherit some of the same malleability of form as the Merfolk, but more readily take to the semi-aquatic lifestyle that's well suited to tending the river-gardens of Amaranth.
