Sahuagin

The Sahuagin (sa-ʊɑː-ɣɪn) also spelt sahuaɣin, were nocturnal aquatic humanoids native to The Cradle. Their common name derived from the Euluska word Sauheromu, meaning night, plus an inflection of the word for people - thus, night people. This was due to their love of attacking ships by night.
