Homebrew Siren Species Details

As they approach rocky coasts, sailors may hear a wonderful tune. The siren is singing this beautiful tune. Its real form is a hybrid between a female humanoid and a bird. Hundreds of years ago, a jealous witch changed their lovely appearance and exiled the fey from the realm.

Vixens of Vengeance: Sirens seek vengeance by luring those who live near the coast. As they go closer to rocky coasts, sailors have been known to ruin their ships.

Fey, the Forgotten: Sirens utilize their shapechange power to return to land on occasion, still angry over the curse that changed their appearance. Once on land, the siren uses all of her charms to entice additional victims.
