Merula Snyde

Merula Snyde is a witch who began attending Hogwarts School of Witchcraft and Wizardry and was sorted into Slytherin. Merula often antagonized Squiggly Squinquargesimus during their time in Hogwarts and remained a persistent rival to them throughout the years.

Early life
Merula's parents were Death Eaters who supported Lord Voldemort. After the Dark Lord's demise, her parents raised her until they were captured and sent to Azkaban. Her mother, being a member of the Frog Choir in her youth, frequently sang to her until her arrest, though she would keep this a secret out of insecurity. She was raised by her aunt, who forbade her from owning any pets, much to her chagrin.

Merula claimed to have attended every Quidditch World Cup since she was born.

Hogwarts
While at Hogwarts Merula frequently bullied other students mostly half-bloods and muggle-borns. At the beginning of her time at Hogwarts, she was bullying Rowan Khanna but Squiggly Squinquargesimus quickly stood up to Merula and from then on the two had a heated rivalry with Merula trying to find the vaults in hope to gain power and knowledge but she was somehow always stopped by Squiggly and the other members of the Guards.

Guards of the unknown
She eventually started her own gang after she was betrayed by Tulip Karasu who used to be Merula's best friend but left to befriend Squiggly. Then when Barnaby lee and Ismelda Murk also became close to Squiggly Merula joined the guards but still kept her rivalry with Squiggly. Merula was present the moment Rowan died and like Squiggly, Ben and Bill she was in a state of shock and mourn.

Later life
After Hogwarts Merula graduated and started working for the Ministry, she eventually found herself a husband and they had children. Merula didn't seek contact with any of the members of the Guards nor her former friends at Hogwarts.
