Black Lake Merchieftainess
Very little is known about Murcus' early life, or even the time when she was pronounced Merchieftainess. Following the Second Task of the Triwizard Tournament, she relayed Harry Potter's actions at the Merpeople village, and his desire to rescue all the hostages, to Albus Dumbledore. She may have been present for the Merpeople's sendoff at Dumbledore's funeral.
Personality and TraitsEdit
Despite Murcus seemed like a lethal and deadly female, she advised Headmaster Albus Dumbledore that Harry came in first, earning Harry second place in the second task.
