The Aventi are a race of aquatic humanoids. Physically, they resemble humans with gills. They are one of only two fully-amphibious races in the setting, the other being the Kua Toa.
The Aventi first made contact with humans in the nation of Vistria. As a token of friendship, they gave the then-king the Friend of the Sea amulet. The Aventi were later subjugated by the Deluvian Empire, who slew most of the Aventi as they were paranoid that amphibious slaves could successfully revolt against their dry-land cities in the Baalian Archipelago.
