P rophetic dreams
Cassandra Trelawney was a powerful Seer and a brilliant witch. She harnessed her ability to become respected and powerful, without becoming a popular sideshow or an expensive preview service for the wealthy. She was the greatest prophet of four centuries, and she knew how to wield her power - and the power of her name.
Generations later, her name is enough for a skeptical headmaster to be unable to refuse to see her nearly talentless descendant. Sybill Trelawney is almost a Squib and quite aware that she was both interviewed and hired only because of her great-great-grandmother's talent and reputation.
Sybill Trelawney holds only the dwindling power of a proud family history. She is a prophet only in her dreams.
The unworthy heir, the false successor, of a great lady. The rest of her family destroyed by Grindelwald, she had no other example to follow but the ancient shining star of Cassandra.
But though the Trelawnies have lost the wit to harness or even recognize their abilities, their power has not yet winked out of existence. It clings desperately to the fringe of reality, not ready to die out completely.
