For Meredith's daughter, see Tegan Bryluen Mary Katherine.

Tegan was mother of Sholto's father, and she is therefore very likely a nightflyer of Sluagh. Meredith talks about her in past tense, so Tegan is probably dead.

Meredith names one of her daughters after Tegan: Tegan Bryluen Mary Katherine, or "Tegan Rose" for short. Sholto is one of Tegan Rose's three fathers, which is why Merry gave Tegan Rose his grandmother's name.

Tegan is first mentioned in A Shiver of Light.
