Greater raven

Greater ravens were the eponymous inhabitants of Ravens Bluff. They had a reputation for predicting the future.

Description
They were glossy black birds with wingspans and dark eyes.

Abilities
Besides their renowned ability to deliver cryptic prophecies- which typically foretold woe either minor or catastrophic- greater ravens had only one other magical ability: the power to curse whoever slew them. At the moment of their death they delivered the curse as a rhyming prophecy; no matter how they were killed the curse could be clearly heard unless a silence spell had been cast over the area- and even then, it only prevented the hearing of the curse, not its effects.
